The way we got/stored background matrices is a bit weird and full of
leftovers from the first attempts at porting renderers. This doesn't
work well with the Jak 2 "other camera" system where some stuff is
rendered with a different camera matrix.
This cleans most of it up. The exception is that the collide mesh
renderer and the additional sprite culling I added still need to peek at
some cached camera matrices.
This fixes the problem where etie uses the wrong matrices for "other
camera" levels. Now the "hole covers" go in the holes in the background
of the throne room.

I havn't tested it yet, but I can almost guarantee that atleast `goalc`
will not work in the slightest!
But the project is atleast fully compiling. My hope is to start
translating some AVX to NEON next / get `goalc` working...eventually.
Saves 16 bits and lets us align the `color_index` field properly.
This shouldn't improve or decrease performance by any noticeable amount
except maybe in really low end systems.
Fixes some mistakes with merc draw modes. The glass in the palace level
no longer writes to the depth buffer (it's "water"):

Also fixes the one-frame flickers when level draw orders change. We
might be able to make this more efficient in the future, but this will
at least fix the frame with nothing drawn.
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.
Favors the `lg` namespace over `fmt` directly, as this will output the
logs to a file / has log levels.
I also made assertion errors go to a file, this unfortunately means
importing `lg` and hence `fmt` which was attempted to be avoided before.
But I'm not sure how else to do this aspect without re-inventing the
file logging.
We have a lot of commented out prints as well that we should probably
cleanup at some point / switch them to trace level and default to `info`
level.
I noticed the pattern of disabling debug logs behind some boolean,
something to consider cleaning up in the future -- if our logs were more
structured (knowing where they are coming from) then a lot this
boilerplate could be eliminated.
