avcodec/mediacodecenc: Add operating_rate option
For example, with
./ffmpeg -operating_rate 400 -hwaccel mediacodec -i test.mp4 -an \
-c:v h264_mediacodec -operating_rate 400 -b:v 5M -f null -
The transcoding speed is 254 FPS.
Without -operating_rate on dec/enc, the speed is 148 FPS.
With -operating_rate on decoder only, the speed is 239 FPS.
