this is done incorrectly, and also needs lots of culling and optimization

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.

Also, emissive surfaces are no importance sampled, so it's noise fest.

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.

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
