1ae5cfe548 rtx: presumably fix gray textures 
Modulate the subsequent bounces with texture color. This makes it
consistent with the way surface lights and dlights work.

5ddeb6853d rtx: fix corrupted geometry 
TLAS creation pattern ended up allocating memory in a temporary region. It was later reused for BLAS data, and subsequently corrupted by TLAS rebuild.

Also fixed memory leak, added freeze-models command, added model debug code into shaders, etc.

2f965b00d4 rtx: read emissive texture params from rad files 
Got rad files from https://github.com/MaestroFenix/Half-Life-Resized-Maps
These seem to work mostly fine and finally levels have recognizable appearance.

28f2c06bdb rtx: cache and destroy model blases 
Unfortunately Xash3D doesn't allow us to destroy models properly.
It doesn't call Mod_ProcessRenderData for all brush models (only map).
And by the time we get into R_Shutdown all models are already gone, so
we can't enumerate and destroy them properly.

01e6a267d5 rtx: fix toilet crash 
Toilet contained brush model with presumably water surfaces which
were not loaded due to how we treat surface flags. That ended up
creating a model with no geometries, which is just rude.
We don't try to render those kind of models now.

ad7b210228 rtx: improve surface lights 
use bsp/pvs-based visibility data for acceleration:
+ fps 5 -> 60
- correctness: some areas have too many lights, which ends up culling visible ones too

also fix shadow artefacts

d6c56d4e1b 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.

379f6ee409 rtx: add static light entities 
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.

a039e7e5ae rtx: add vk_rtx_reload command to reload rtx.comp.psv shader 
This allows faster shader iterations. Do `bind z vk_rtx_reload`.
Still need to recompile the shader outside xash process manually.
