water111 3ee2b4423c [decompiler] Cleanup for Jak 3 (#3845)
This PR does a few cleanups:
- improve method names/comments/flags for `enemy.gc` and a few other
files
- fix `new-stack-matrix0` not working for jak 3
- add `matrix-copy!` detection for jak 3
- add `vector-copy!` detection

---------

"A transform with:
- type information (child of [[basic]])
- rotation stored as quaternion
- velocity information.
This is a very commonly used type to represent the position of an in-game object.
The `root` of a process-drawable (the parent 'in-game object' type) is a [[trsqv]].
Additionally, the collision system uses [[trsqv]] as the parent type for foreground
collision objects ([[collide-shape]], [[collide-shape-moving]]).
As a result, this type has a lot of weird methods and extra stuff hidden in it."
