lavf/qsv_scale: add scaling modes support
low_power mode will use a fixed HW engine (SFC), thus can offload EU usage. high quality mode will take EU usage (AVS sampler). Performance and EU usage (Render usage) comparsion on Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz: High quality mode : ffmpeg -hwaccel qsv -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal_2000frames.h264 \ -vf scale_qsv=w=1280:h=736:mode=hq -f null - fps=389 RENDER usage: 28.10 (provided by MSDK metrics_monitor) Low Power mode: ffmpeg -hwaccel qsv -c:v h264_qsv -i ~/bbb_sunflower_1080p_30fps_normal_2000frames.h264 \ -vf scale_qsv=w=1280:h=736:mode=low_power -f null - fps=343 RENDER usage: 0.00 Low power mode (SFC) may be disabled if not supported by MSDK/Driver/HW, and replaced by AVS mode interanlly.
