averne 98412edfed lavc: add a ProRes Vulkan hwaccel ...

Add a shader-based Apple ProRes decoder.
It supports all codec features for profiles up to
the 4444 XQ profile, ie.:
- 4:2:2 and 4:4:4 chroma subsampling
- 10- and 12-bit component depth
- Interlacing
- Alpha

The implementation consists in two shaders: the
VLD kernel does entropy decoding for color/alpha,
and the IDCT kernel performs the inverse transform
on color components.

Benchmarks for a 4k yuv422p10 sample:
- AMD Radeon 6700XT:   178 fps
- Intel i7 Tiger Lake: 37 fps
- NVidia Orin Nano:    70 fps
