[vulkan] Start moving towards a deferred renderer After getting lights even vaguely working for alias models, I realized that it just wasn't going to be feasible to do nice lighting with forward rendering. This gets the bulk of the work done for deferred rendering, but still need to sort out the shaders before any real testing can be done.

[scene] Add flags for finer rendering control This takes care of rockets and lava balls casting shadows when they shouldn't (rockets more because the shadow doesn't look that nice, lava balls because they glow and thus shouldn't cast shadows). Same for flames, though the small torches lost their cool sconce shadows (need to split up the model into flame and sconce parts and mark each separately).

[vulkan] Implement team colors It's not quite as expected, but that may be due to one of msaa, the 0-15 range in the palette not being all the way to white, the color gradients being not quite linear (haven't checked yet) or some combination of the above. However, it's that what should be yellow is more green. At least the zombies are no longer white and the ogres don't look like they're wearing skeleton suits.

[vulkan] Use palette lookups for top/bottom colors As the RGB curves for many of the color rows are not linearly related, my idea of scaling the brightest color in the row just didn't work. Using a masked palette lookup works much better as it allows any curves. Also, because the palette is uploaded as a grid and the coordinates are calculated on the CPU, the system is extendable beyond 8-bit palettes. This isn't quite complete as the top and bottom colors are still in separate layers but their indices and masks can fit in just one, but this requires reworking the texture setup (for another commit).

[vulkan] Abandon bindless rendering At least for now, it is more trouble than it is worth as it (or my implementation of it) breaks lavapipe and renderdoc.

[vulkan] Support multiple render passes Multiple render passes are needed for supporting shadow mapping, and this is a huge step towards breaking the Vulkan render free of Quake, and hopefully will lead the way for breaking the GL renderers free as well.

[model] Make alias skin loading a batch operation Really, this won't make all that much difference because alias models with more than one skin are quite rare, and those with animated skin groups are even rarer. However, for those models that do have more than one skin, it will allow for reduced allocation overheads, and when supported (glsl, vulkan, maybe gl), loading all the skins into an array texture (since all skins are the same size, though external skins may vary), but that's not implemented yet, this just wraps the old one skin at a time code.
