avdevice/lavfi: output wrapped AVFrames
This avoids an extra copy of potentially quite big video frames. Instead of copying the entire frames data into a rawvideo packet it packs the frame into a wrapped avframe packet and passes it through as-is. Unfortunately, wrapped avframes are set up to be video frames, so the audio frames continue to be copied. Additionally, this enabled passing through video frames that previously were impossible to process, like hardware frames or other special formats that couldn't be packed into a rawvideo packet.
