[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.
