libavfilter/vf_vpp: Add common filters of the qsv vpp

Add common filters of the qsv vpp features including scale,denosie,
deinterlace,frc,crop and procAmp.

Performance will be significantly reduced in the test if using cascade
mode just like qsv framerate + qsv scale + qsv deinterlace + qsv denoise in
separated way no matter in system or video memmory cases.
And the code is so redundant because so much the same just as session and
surface's creation and management.
So we add a common qsv filter.

Usage:
-hwaccel qsv -c:v h264_qsv -r 25 -i in -vf
vpp_qsv=w=iw/2:h=400:deinterlace=1:framerate=60:detail=50:denoise=50
-b 2M -maxrate 3M -c:v h264_qsv -y out.h264
