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.

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.

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.

And get RTX picture we deserve (i.e. glitchy and incorrect).

e0ee4b756b rtx: make it draw yellow screen
this basically checks that acceleration structurs are building without
any vulkan errors (we still don't know whether they are bulding with
correct geometry though).

we also have compute shader pipeline ready for ray tracing (yay)
but it doesn't do any raytracing yet
