lavf/qsvvpp: add extra_hw_frames support
extra_hw_frames is needed for some cases.
(eg: qsv decoding + qsv vpp + qsv look_ahead encoding, transcoding
failed if no extra_hw_frames supported:
ffmpeg -hwaccel qsv -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal_2000frames.mp4 \
-vf vpp_qsv=w=1280:h=720:extra_hw_frames=100 -v verbose -c:v h264_qsv \
-look_ahead 1 -look_ahead_depth 100 out1.mp4
)
