Goober5000andClaude Fable 5.1 37b0b6ea82 Standardize isValid across the Lua API by making the types auto-generate it (#7761)
* Automatically generate the isValid() Lua API function for handle types

If an ADE object's stored type has an isValid() member, ade_obj now registers an isValid function for it automatically.  An explicit ADE_FUNC(isValid, ...) declared after the ADE_OBJ replaces the generated one, so types with special semantics (e.g. sound) keep their own.  The 67 hand-written functions that merely delegated to the member are removed, and 26 types that previously exposed no isValid() gain one.

* Add ADE_OBJ_VALIDATOR for index-based Lua handles

Int-index handles (shipclass, weaponclass, team, etc.) can now declare their validity predicate with a single ADE_OBJ_VALIDATOR or ADE_OBJ_VALIDATOR_RANGE line after the ADE_OBJ.  The registered validator drives the generated isValid() function and is also honored by ade_set_args when the mod table asks for nil instead of invalid objects, which previously never applied to these handles.  The 19 hand-written range-check functions are replaced, and loadout_ship, default_primary, default_secondary, and support_rearm_pool_team gain isValid().  Add a validator to HudGauge while we're at it.

Also fully qualify the scripting namespace in LuaConvert.h so its templates can be instantiated from the unit tests.

Goober5000 592eefb60f scripting refactor to compose handle types
Several handle types in the scripting API used inheritance where composition would be more appropriate.  This refactors those types, as well as removing the various handle types that were just aliases for `model_h`.  These are just the C++-side types; all the Lua types remain as-is.

This also refactors `sound_h` to move the previous `isSoundValid` to `isValid` so that `ade_set_args` will work properly for sounds with the `Lua_API_returns_nil_instead_of_invalid_object` flag.  The subclassing from `sound_entry_h` was removed and the "full validity check" was moved to `isValidWithEntry`.  The Lua side remains unaffected, but additional documentation was added to clarify the usage.

Follow-up to #6009 and prerequisite to #6006 due to the `isValid` refactor for `sound_h`.

asarium ce1ea75714 Add unload function for freeing audio memory of a soundfile handle
This can be used by scripts for explicitly freeing up some memory when
necessary.

asarium ad54f588bb Use strongly typed handles for sound handles
This is similar to the other changes I already posted. Here the sound
instance handles are converted to their own handle type which will make
it easier to use the sound API.

asarium 9dfb8faea3 Use strongly-typed handles for sound entries
This converts the previous int handles to a strongly-typed wrapper
handle which will make the API more self-documenting and will ensure
that wrongly used handles are detected at compile time.

I already found a few mistakes with these changes which I also fixed
here.

asarium 8f06e338a4 Add typesafe handle types and use it in game sound system
This adds a new class which allows to create type safe resource handle
types. At the moment, the engine uses ints pretty much everywhere for
providing handles to resources created by the specific subsystems. Since
all ints are the same to the C/C++ typesystem it is perfectly legal to
pass a sound handle to the graphics API as a buffer handle which will
obviously cause issues.

This adds a new type called "ID" which is a wrapper class for a generic
handle but with added type safety. An instance of this class cannot be
passed to a function expecting another type of handle which provided
compile-time type safety for these APIs.

As an initial test I converted the game sound handles to this new type.
I already found a bug in the mainhall system thanks to this new type.
The mainhall used the game sound handles as sound instance handles which
probably meant that that specific code never really worked right. I
removed the code since there was no better alternative for fixing it.

asarium 0ff8a2c159 Add support for multiple sounds in one game sound entry
This adds support for specifying multiple sounds for a single game sound
entry. The engine then selects which sound will be played based on the
strategy provided by the game data. This required a few changes to some
of the game code since previously every game sound had exactly one sound
file attached to it. The most notable change is that it is no longer
possible to determine the exact duration a sound can have so instead the
new code computes the maximum duration a sound can have and uses that
where appropriate.

This also adds support for randomizing the pitch and volume of the sound
to provide a more varied experience even if only a single sound is used.

One possible issue that exists is that the "sequential" strategy only
works globally at the moment so if two sources use the same game sound
concurrently then the two sources will share the sequence of sounds
since there is no sound instance data at the moment. That can be added
in a future change but should not present a huge issue for most
use-cases.

Visual Studio on Appveyor somehow causes deprecation error on _our_
definition of vsprintf. I have no idea why these changes introduced this
warning but I won't debug Visual Studio compiler bugs that I can't
reproduce with my Visual Studio version so I just disabled those
warnings.
