Fixes the pillars being transparent (but is a bit of a hack), the desert
sand not having texture filtering, and the "No memory card" on the title
screen with debug mode off.

I finally went through and worked out the math for the camera matrix,
and improved how it works for PC rendering. I was able to finally avoid
the double perspective divide issue, which I always thought would cause
accuracy issues.
This will help tfrag, tie (no envmap), shrub, and hfrag have less
z-fighting in cases where the camera and the thing you're looking at are
pretty close, but the entire level is far from the origin - like jak 3
temple. I was able to modify the camera matrix so we don't have to do
all the weird scaling/addition in the shader.
Here's a screenshot from the temple oracle checkpoint, cropped from 4k.
This used to have a lot of fighting issues.

It doesn't help issues where the thing you're looking at is very far
away (jak 1 mountains, some jak 2 city stuff). It also doesn't help with
jak's skirt/scarf, since those use a different renderer.
There's definitely more to do here, but this is a good starting point
and proof that I can at least figure out the math.

This only applies to the background for now:
- support for alpha for vertex colors in custom levels
- switch time of day palette generation from octree to k-d tree
- support for alpha masking in custom levels
- support for transparent textures
- support for envmap in custom levels

For now, this just adds sky (clouds and fog), darkjak, and skull gem.
There are some unknown issues with drawing the skull gems still, but I
think it's unrelated to texture animations.
Also fixes https://github.com/open-goal/jak-project/issues/3523
This adds hfrag, but with a few remaining issues:
- The textures aren't animated. Instead, it just uses one texture.
- The texture filtering isn't as good as at it could be.
I also cleaned up a few issues with the background renderers:
- Cleaned up some stuff that is common to hfrag, tie, tfrag, shrub
- Moved time-of-day color packing stuff to FR3 creation, rather than at
level load. This appears to reduce the frame time spikes when a level is
first drawn by about 5 or 6 ms in big levels.
- Cleaned up the x86 specific stuff used in time of day. Now there's
only one place where we have an `ifdef`, rather than spreading it all
over the rendering code.
This fixes issues with certain Jak 3 levels not rendering because there
is a mismatch between the DGO name, nickname and real level name (bsp
name).
FR3s use a different filename, so you can delete the ones you have after
this is merged.
This affects custom levels, but I don't have that toolchain set up so
someone else will have to test that.
This includes all the collision stuff needed to spawn `target`,
decompiles the sparticle code and adds some of the PC hacks needed for
merc to run (it doesn't work quite right and looks bad, likely due to a
combination of code copied from Jak 2 and the time of day hacks).
There are a bunch of temporary hacks (see commits) in place to prevent
the game from crashing quite as much, but it is still extremely prone to
doing so due to lots of missing functions/potentially bad decomp.

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.

Added framework to do texture animations entirely in C++. Currently only
works on relatively simple ones, and doesn't handle updating all
parameters - only the speeds.
Connected texture animations to merc and tfrag for skull gems, dark
bomb, and scrolling conveyors.
Cleaned up Tfragment/Tfrag3, which used to be two classes. This was one
of the first C++ renderers, so it had a weird design.
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.
Disables the fog hack for Jak 2, where it's not useful and kind of
breaks in most levels which rely on dark vertices that aren't underwater
(e.g. city windows).
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.
This adds environment mapping support to `Merc2`, and turns it on for
Jak 1 and Jak 2.
- The performance is much better
- Jak 1 can be toggled back to the old behavior with `(set! *emerc-hack*
#f)`. The new environment mapping is identical to the old one everywhere
I checked.
- Jak 1 still falls back to generic for ripple/texscroll/blerc/eyes -
there's still no dynamic texture or vertex updating support. The eye
detection stuff will sometimes flag stuff as eyes which is not eyes,
which is fine, but means that generic will be used in some places where
emerc could be used. For example, the shiny plates on jak's arm will be
drawn with generic because jak has eyes.
- Jak 2 hasn't been checked super carefully against PCSX2 yet.
- Jak 2 still isn't technically using emerc, but instead putting emerc
models in the merc bucket.
- The interface to merc is a lot different now and totally custom
OpenGOAL DMA code. The original merc drawing asm doesn't run anymore.
- The FR3 format changed
- Something funky going on with foreground lighting in escape, but
doesn't seem to be related to this change?
Performance comparison, jak 1, in likely the most generic-merc heavy
spot:


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.
