wm4 cda7203934 mp_image_pool: add helper functions for FFmpeg hw frames pools
FFmpeg has its own rather "special" image pools (AVHWFramesContext)
specifically for hardware decoding. So it's not really practical to use
our own pool implementation. Add these helpers, which make it easier to
use FFmpeg's code in mpv.
