Subject: [PATCH 2/3] radv/radix_sort: Vendor the radix sort dispatch code
This needs to be done so we can optimize it for occpuancy when building
multiple acceleration structures in parallel. Changes to the original
code:
- Change // to /* */
- clang-format
- Replace vkCmd calls with calls to the driver entrypoints
- Add a light weight info struct
- Use radv_fill_buffer directly

Subject: [PATCH 3/3] radv: Perform multiple sorts in parallel
This was the last part that didn't scale with multiple infos. Reducing
the amount of barriers in this case improves DOOM Eternal performance by
50%. (Running with low resolution)
