vk: revert -nort commit
...
`rt_force_disable` is perfectly fine, it just needs to be written into
either `vk.cfg` or `video.cfg` to work. Other configs are read *after*
`R_VkInit()` function get called.

vk: rt: add workaround for holes in geometry
...
Once upon a time, there were some BLASes. There were the BLASes for dynamic geometry, that were to be used every frame to draw very dynamic things, like sprites and beams. They were initialized at the very begining of the renderer's lifetime, and were expected to live happily for the entire process duration.
However, an evil NewMap appeared. It didn't care abount anything or anyone, so when it came, it just cleared all the allocators, and allowed other BLASes to be allocated into the same space as dynamic BLASes were already given. This made BLASes live on top of each other, use each others toys and make them fight. They weren't happy.
So we just kill them and creat them again from scratch, when the evil NewMap comes.
The end.

`throughput` should be scaled based on BRDF. I.e. diffuse bounces should

vk: rt: degrade spatial image quality by box blur denoiser
...
Our gaussian blur is incorrect, as it doesn't preserve luminance, and
the final imaga ends up being darker than it should be.
Do a box blur as a simple test. It does result in a correctly looking
white furnace test image (modulo square blocks and luminance leaking).
