d/jak2: pass through all simple / non-blocked *-part, *-ocean and *-scenes files (#2048)

A big one...

I figure even if we would like to change the way the particle/scene code
is output -- it'd be easier to find patterns with it all decompiled.

I've updated my script so it can easily be used to mass update these
files:
```bash
task update-gsrc-glob GLOB="**/*-part*.gc"
```
> for example will update gsrc files with `part` in their name -- if
they are in ref tests (so uncompleted ones aren't touched)

I found a few issues along the way that I'll have to make issues for
soon.
