3b2a9410ef avcodec/decode: Only use ff_progress_frame_get_buffer() with blank input 
All users (namely HEVC) that use ff_progress_frame_alloc()
should just use ff_thread_get_buffer(). Using
ff_progress_frame_get_buffer() is not a must; it is merely
a convenience wrapper.

29b85cd4b8 vulkan_ffv1: add cached symbol reader for AMD 
Speeds up everything on AMD by 3x.
This uses 32 local invocations to load state into cache, as well
as to do the RCT faster.

e040c087c7 vulkan: add support for expect/assume 
This commit adds support for compiler hints.

a sizeable 10% speedup on 4k.

77f777d925 ffv1/vulkan: redo context count tracking and quant_table_idx management 
This commit also makes it possible for the encoder to choose a different
quantization table on a per-slice basis, as well as adding this capability
to the decoder.

Also, this commit fully fixes decoding of context=1 encoded files.

66b8c92df2 vulkan_ffv1: cache only 2 lines when decoding RGB 
This reduces the intermediate VRAM used for RGB decoding by a
factor of 100x for 6k video.
This also speeds the decoder up by 16% for 4k RGB24 and 31% for 6k video.

This is equivalent to what the software decoder does, but with less pointers.
