This PR is a combination of
https://github.com/open-goal/jak-project/pull/2507 and some additional
changes to port Shadow VU1 to OpenGL. As far as I can tell, it's
working.

Definitely needs a clean up pass, but I think the functionality is very
close.
There's a few "hacks" still:
- I am using the emerc logic for environment mapping, which doesn't care
about the length of the normals. I can't figure out how the normal
scaling worked in etie. I want to do a little bit more experimentation
with this before merging.
- There is some part about adgifs for TIE and ETIE that I don't
understand. The clearly correct behavior of TIE/ETIE is that the alpha
settings from the adgif shader are overwritten by the settings from the
renderer. But I can't figure out how this happens in all cases.
- Fade out is completely disabled. I think this is fine because the
performance difference isn't bad. But if you are comparing screenshots
with PCSX2, it will make things look a tiny bit different.
The VU programs for the ocean renderer have changed a bit and
`ocean-texture` has a bunch of new stuff, otherwise things are
relatively similar to Jak 1.
This is the first time I used mips2c and I'm not sure I did it 100%
right, so that should be double-checked.
Some notes:
- `draw-prototype-inline-array-shrub` can probably be decompiled but I'm
not comfortable doing this function myself. It's got a ton of inline
assembly (or at least I think it's inline assembly) and is very long. I
left this marked as asm for now but I am confident in the function
definition.
- The VU program is identical to Jak 1 (yay)
- There's some new `dma-test` stuff at the end of the file, not really
sure what it's doing but it runs in the top-level.
The merc VU1 program is identical to Jak 1. Jak 2's merc is doing some
new texture login stuff and the DMA buffer setup is a bit different, but
overall very similar.
