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.

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.

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.

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.
