ffmpeg: Support setting the hardware device to use when filtering
This only supports one device globally, but more can be used by
passing them with input streams in hw_frames_ctx or by deriving new
devices inside a filter graph with hwmap.
(cherry picked from commit e669db76108de8d7a36c2274c99da82cc94d1dd1)
