decomp: tomb-* files, target-indax, grunt-mech, breakable-wall, pillar-collapse, mechtest-obs, ruins-obs (#2114)

Manual patches in:

- `tomb-boulder`: a few `ppointer->handle`s (I think) were not being
decompiled properly (all used in combination with `clone-anim-once`)
- `ruins-obs`, `pillar-collapse`: `art-joint-anim` casts
- `tomb-beetle`: commented out a call to `shadow-control-method-14` that
was crashing the game when spawning the beetles
- `grunt-mech`: commented out `(.mula.s)` instruction

Notes:
- `enemy-info`'s `idle-anim-script` is most likely a `(pointer
idle-control-frame)`, however, some `nav-enemy-info` labels set it to
`#f` (first encountered in `tomb-beetle`, but also present in `hal`,
`roboguard` and `metalkor-setup`), which crashes the decompiler. This
may become a problem in the future when we eventually get to these
files. For this PR, I made `tomb-beetle` decompile with
`idle-anim-script` set to `#f` and have not noticed any issues/crashes
with that.
- `tomb-boulder` compiles and doesn't crash, but when trying to play the
Daxter chase sequence, the boulder sometimes either spawns at the origin
or spawns in the correct place, but doesn't move.
