This commit adds a ProRes RAW hardware implementation written in Vulkan.
Both version 0 and version 1 streams are supported.
The implementation is highly parallelized, with 512 invocations dispatched
per every tile, with generally 4k tiles on a 5.8k stream.
Thanks to unlord for the 8-point iDCT.
Benchmark for a generic 5.8k RAW HQ file:
6900XT: 63fps
7900XTX: 84fps
6000 Ada: 120fps
Intel: 9fps
