decomp3: spawn target, add merc and particle buckets and some temporary hacks (#3445)
This includes all the collision stuff needed to spawn `target`,
decompiles the sparticle code and adds some of the PC hacks needed for
merc to run (it doesn't work quite right and looks bad, likely due to a
combination of code copied from Jak 2 and the time of day hacks).

There are a bunch of temporary hacks (see commits) in place to prevent
the game from crashing quite as much, but it is still extremely prone to
doing so due to lots of missing functions/potentially bad decomp.

Decompile foreground and bones (#3427)
Small fix to decompiler when the original compiler uses `ra` register.
This seems to happen in "normal" code very rarely - perhaps they
manually specified this in an `rlet`.

Start figuring out buckets/textures for Jak 3.

The foreground code is not yet modified for PC - I want to wait until
the game is running, since it is too hard to do it now.

deps: update fmt to latest version (#3403)
This updates `fmt` to the latest version and moves to just being a copy
of their repo to make updating easier (no editing their cmake / figuring
out which files to minimally include).

The motivation for this is now that we switched to C++ 20, there were a
ton of deprecated function usages that is going away in future compiler
versions. This gets rid of all those warnings.

Additionally:

- Detection of non-virtual state inheritance

by `stack-size-set!` calls
- Fix for integer multiplication with `r0`
- Fixed detection for the following macros:
	- `static-attack-info`
- `defpart` and `defpartgroup` (probably still needs adjustments, uses
Jak 2 implementation at the moment)
- `sound-play` (Jak 3 seems to always call `sound-play-by-name` with a
`sound-group` of 0, so the macro has been temporarily defaulted to use
that)

One somewhat significant change made here that should be noted is that
the return type of `process::init-from-entity!` was changed to `object`.
I've been thinking about this for a while, since it looks a bit nicer
without the `(none)` at the end and I have recently encountered init
methods that early return `0`.

Decompile joint, collide-func, clean up joint decompression code for all games (#3369)
I finally read through all the joint code and wrote up some
documentation. I think this will be really helpful when we try to
understand all the functions in `process-drawable`, or if somebody ever
wants to import/export animations.

This switches all three games to using a new faster GOAL joint
decompressor. It is on by default, but you can go back to the old
version by setting `*use-new-decompressor*` to false.

Also fix the log-related crash, fix the clock speed used in timer math.

jak3: fix all-types file order (#3316)
In #3300, `per_object` in `ObjectFileDB::ir2_analyze_all_types()` was
changed to an `unordered_map`, which messed with the object file order
in `all-types`. This fixes the issue by going through each object file
in order and then looking up the type info from the map instead of
iterating through the map.

This also removes the method IDs from the old method comments and adds a
stub for the `new` method if there is an old method comment for it, in
order to stay consistent with the rest of the method list.

Jak3 Build Environment (#3098)
This sets out the bones of a Jak 3 build, many things are stubbed out,
guessed, or copied from Jak 2 but it should at least be good enough to:
run `task set-game-jak3`
launch the repl
run builds from the repl

build outputs themselves are untested but the build itself runs without
errors

Fix cases of string formatting with non string literals (#3304)
The logger used in `goalc` tries to print an already-formatted string
`message` using `fmt::print(message);` Usually this doesn't cause
problems, but if you try to print, for example, an exception that has
special characters (notably `{`) it will try to do another round of
formatting/replacements, despite not having any args to replace with,
which ends up throwing another exception. This is why errors when
parsing custom level JSON cause the REPL to exit.

I've hopefully identified all the various instances of this across the
codebase

deftype and defmethod syntax major changes (#3094)
Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
  - the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
  ((vec    vector  :inline)
   (flags  int32   :overlay-at (-> vec w))
   )
  )
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes #3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.

Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes #3093.

[goalc] Cleaned up speedups (#3066)
Started at 349,880,038 allocations and 42s

- Switched to making `Symbol` in GOOS be a "fixed type", just a wrapper
around a `const char*` pointing to the string in the symbol table. This
is a step toward making a lot of things better, but by itself not a huge
improvement. Some things may be worse due to more temp `std::string`
allocations, but one day all these can be removed. On linux it saved
allocations (347,685,429), and saved a second or two (41 s).
- cache `#t` and `#f` in interpreter, better lookup for special
forms/builtins (hashtable of pointers instead of strings, vector for the
small special form list). Dropped time to 38s.
- special-case in quasiquote when splicing is the last thing in a list.
Allocation dropped to 340,603,082
- custom hash table for environment lookups (lexical vars). Dropped to
36s and 314,637,194
- less allocation in `read_list` 311,613,616. Time about the same.
- `let` and `let*` in Interpreter.cpp 191,988,083, time down to 28s.

[opengoal] make none a child of object (#3001)
Previously, `object` and `none` were both top-level types. This made
decompilation rather messy as they have no LCA and resulted in a lot of
variables coming out as type `none` which is very very wrong and
additionally there were plenty of casts to `object`. This changes it so
`none` becomes a child of `object` (it is still represented by
`NullType` which remains unusable in compilation).

This change makes `object` the sole top-level type, and the type that
can represent *any* GOAL object. I believe this matches the original
GOAL built-in type structure. A function that has a return type of
`object` can now return an integer or a `none` at the same time.
However, keep in mind that the return value of `(none)` is still
undefined, just as before. This also makes a cast to `object`
meaningless in 90% of the situations it showed up in (as every single
thing is already an `object`) and the decompiler will no longer emit
them. Casts to `none` are also reduced. Yay!

Additionally, state handlers also don't get the final `(none)` printed
out anymore. The return type of a state handler is completely
meaningless outside the event handler (which is return type `object`
anyway) so there are no limitations on what the last form needs to be. I
did this instead of making them return `object` to trick the decompiler
into not trying to output a variable to be used as a return value
(internally, in the decompiler they still have return type `none`, but
they have `object` elsewhere).

This PR adds detection of the `launch-particles` and `seconds-per-frame`
macros to the decompiler, removing a lot of bloat and hiding many

I also added `og:preserve-this` comments to as many manual patches and
comments as I could, which will soon be used in conjunction with CI to
hopefully catch any regressions in future big decomp update PRs.

I have some concerns about the `launch-particles` macro (more details in

yet.

start blit-displays decomp & renderer + improve decompilation of some DMA macros (#2616)
Adds sprite distort, fixes buggy sprite rendering in progress, adds
scissoring support (used in various scrolling menus) and a very basic
implementation of `blit-displays`. This is enough to make the fade
effect in the progress menu work, along with all the menus working
properly without needing to use the REPL. This does not make screen
flipping and the filter when failing a mission work.

Added support in the decompiler for detecting `dma-buffer-add-gs-set`
and `dma-buffer-add-gs-set-flusha` and updated all of the Jak 2 code to
use it. Readability improved!

Fixes decompiler issue with `with-dma-buffer-add-bucket` not inlining
forms which broke syntax. Fixes store error warnings showing up for
non-existent stores, there is now a dedicated pass for this at the end.

I started work on making `BITBLTBUF` stuff work in the DirectRenderer,

split new pc features in some files into their own code files + address some old issues + ripple graphics improvements (#2216)
Moves PC-specific entity and debug menu things to `entity-debug.gc` and
`default-menu-pc.gc` respectively and makes `(declare-file (debug))`
work as it should (no need to wrap the entire file in `(when
*debug-segment*` now!).

Also changes the DGO descriptor format so that it's less verbose. It
might break custom levels, but the format change is very simple so it
should not be difficult for anyone to update to the new format. Sadly,
you lose the completely useless ability to use DGO object names that
don't match the source file name. The horror!

I've also gone ahead and expanded the force envmap option to also force
the ripple effect to be active. I did not notice any performance or
visual drawbacks from this. Gets rid of some distracting LOD and some
water pools appearing super flat (and pitch back for dark eco).

Fixes #1424

decomp: citizen-* files, metalhead-* files, civilian, guard, hal3-course (#2194)
No more ghost town!

Manual patches:

- `hal3-course`: In `(anon-function 17 hal3-course)`, the decompiler is
doing something strange with `s3-0` that fails to compile, so I just
removed the `set!` and inlined the condition in the `when`.
- `guard`: Rewrote `(.mula.s)` stuff

docs: add support for :override-doc in method declarations as well as documenting state handlers (#2139)
Adding support for better child-type method docstrings. This is a
problem unique to methods.

Usually, a child-type will have the same signature and a common name
will apply, but the implementation is different. This means, you
probably want a different docstring to describe what is happening.

Currently this is possible to do via `:replace`. The problem with
replace is two fold:
- a replaced method ends up in the generated `deftype`...because you
usually change the signature!
- we don't put docstrings in the `deftype` in normal GOAL, this is just
something we do for the `all-types` file (they go in the `defmethod`
instead)
- more importantly, this means anytime you now want to change the
parent's name/args/return type -- you have to apply that change
everywhere.

So this is a better design you can now just declare the method like so:
```clj
(:override-doc "my new docstring" <method_id>)
```

And internally a pseudo-replaced method will be added, but it will
inherit everything from the parent (except the docstring of course)

Unrelated - I also made all the keyword args for declaring methods not
depend on ordering

This also adds support for documenting virtual and non-virtual state
handlers. For example:

```clj
  (:states
    (part-tester-idle (:event "test") symbol))
```

or

```clj
(idle () _type_ :state (:event "test") 20)
```

I will probably add the ability to give some sort of over-view docstring
at a later date.
