Add hfrag, clean up some background renderer stuff (#3509)
This adds hfrag, but with a few remaining issues:
- The textures aren't animated. Instead, it just uses one texture.
- The texture filtering isn't as good as at it could be.

I also cleaned up a few issues with the background renderers:
- Cleaned up some stuff that is common to hfrag, tie, tfrag, shrub
- Moved time-of-day color packing stuff to FR3 creation, rather than at
level load. This appears to reduce the frame time spikes when a level is
first drawn by about 5 or 6 ms in big levels.
- Cleaned up the x86 specific stuff used in time of day. Now there's
only one place where we have an `ifdef`, rather than spreading it all
over the rendering code.

Port bones.gc math to GOAL (#3425)
Reverse engineer the skinning matrix calculation and port to GOAL. This
is about 3x faster than the MIPS2c version.

As usual, there is a `*use-new-bones*` flag to go back to the old
version.

Fix for a bug in the compiler's `.div.vf` implementation (only happens
if src/dst are the same), and fix for a typo in the register allocator
that would sometimes cause it not to consider xmm8-xmm15.

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] Decompile gcommon (#3321)
Decompile `gcommon`. I adjusted the spacing of docstring comments, and
removed some spammy decompiler warning prints.

I also added some random notes I had on VU programs from jak1/jak2. They
are not polished, but I think it's still worth including since we'll
have to go through them again for jak 3.

[jak2] float patch for bogus collide frags (#2686)
Should fix https://github.com/open-goal/jak-project/issues/2679

Here's a test program that will trigger the bug when near these guards:
```lisp
(define *cquery* (new 'global 'collide-query))

(defun test-bad-collide ()
  (let ((lower (new 'static 'vector  :x 1681893.8750  :y 61314.2031 :z 345208.6562 :w 1.))
        (upper (new 'static 'vector :x 1701603.8750 :y  67624.0625 :z 357881.0312 :w 1.))
        ;(cquery (new 'stack-no-clear 'collide-query))
        )
    (set! (-> *cquery* collide-with) (the-as collide-spec 1))
    (set! (-> *cquery* ignore-process0) #f)
    (set! (-> *cquery* ignore-process1) #f)
    (set! (-> *cquery* ignore-pat) (new 'static 'pat-surface :noentity #x1 :nojak #x1 :probe #x1 :noendlessfall #x1))
    (set! (-> *cquery* action-mask) (collide-action solid))
    (set! (-> *cquery* bbox min quad) (-> lower quad))
    (set! (-> *cquery* bbox max quad) (-> upper quad))
    (format 0 "doing collide...~%")
    (fill-using-bounding-box *collide-cache* *cquery*)
    (format 0 "have ~d and ~d~%" (-> *collide-cache* num-tris) (-> *collide-cache* num-prims))
    )
  (none)
  )
```

As far as I can tell, there's a totally invalid collide-hash with an
inside `axis-scale.z`. On the PS2, it gets ignore because of how
float->int works for floats that are too big. On PC, it ends up using a
negative value and loop forever.

[jak2] combined shadow work PR (#2632)
This PR is a combination of
https://github.com/open-goal/jak-project/pull/2507 and some additional
changes to port Shadow VU1 to OpenGL. As far as I can tell, it's
working.

[jak 2] ETIE (#2326)
Definitely needs a clean up pass, but I think the functionality is very
close.

There's a few "hacks" still:
- I am using the emerc logic for environment mapping, which doesn't care
about the length of the normals. I can't figure out how the normal
scaling worked in etie. I want to do a little bit more experimentation
with this before merging.
- There is some part about adgifs for TIE and ETIE that I don't
understand. The clearly correct behavior of TIE/ETIE is that the alpha
settings from the adgif shader are overwritten by the settings from the
renderer. But I can't figure out how this happens in all cases.
- Fade out is completely disabled. I think this is fine because the
performance difference isn't bad. But if you are comparing screenshots
with PCSX2, it will make things look a tiny bit different.

[merc2] Support emerc (#2147)
This adds environment mapping support to `Merc2`, and turns it on for
Jak 1 and Jak 2.

- The performance is much better
- Jak 1 can be toggled back to the old behavior with `(set! *emerc-hack*
#f)`. The new environment mapping is identical to the old one everywhere
I checked.
- Jak 1 still falls back to generic for ripple/texscroll/blerc/eyes -
there's still no dynamic texture or vertex updating support. The eye
detection stuff will sometimes flag stuff as eyes which is not eyes,
which is fine, but means that generic will be used in some places where
emerc could be used. For example, the shiny plates on jak's arm will be
drawn with generic because jak has eyes.
- Jak 2 hasn't been checked super carefully against PCSX2 yet.
- Jak 2 still isn't technically using emerc, but instead putting emerc
models in the merc bucket.
- The interface to merc is a lot different now and totally custom
OpenGOAL DMA code. The original merc drawing asm doesn't run anymore.
- The FR3 format changed
- Something funky going on with foreground lighting in escape, but
doesn't seem to be related to this change?

Performance comparison, jak 1, in likely the most generic-merc heavy
spot:
