rtx: add emissive surfaces/textures
...
This is a massive hack, because we hardcoded some valve/lights.rad file
right into vk_rtx.c, and this is most certainly is not correct data. We
expect maps to have more custom rad file entries.
TODO: consult https://github.com/MaestroFenix/Half-Life-Resized-Maps
Also, emissive surfaces are no importance sampled, so it's noise fest.

This was an attempt to add map lighting w/o lightmaps. Unfortunately
there are just not enought of them to explain all light in maps. We're
missing something else. A lot of it.

separate buffer space allocation from buffer uploading
...
Now each geometry is first allocated a slot with VK_RenderBufferAlloc,
and then VK_RenderBufferLock/Unlock are used to upload buffer contents.
This allow for two things:
1. Uploading buffer data to GPU memory on/after Unlock.
2. (Re)building BLAS for RTX on/after Unlock.
These buffers are now directly referenced by render_draw_t, which also
will be helpful in the future for both renderers.

Now rendering submodules specify their colors and matrices using
VK_RenderState global stat api. This is a trade-off between making all
