lavu/hwcontext_qsv: Add support for AV_PIX_FMT_BGRA.
RGB32(AV_PIX_FMT_BGRA on intel platforms) format may be used as overlay with alpha blending.
So add AV_PIX_FMT_BGRA format support.
One example of alpha blending overlay: ffmpeg -hwaccel qsv -c:v h264_qsv -i BA1_Sony_D.jsv
-filter_complex 'movie=lena-rgba.png,hwupload=extra_hw_frames=16[a];[0:v][a]overlay_qsv=x=10:y=10'
-c:v h264_qsv -y out.mp4
Rename RGB32 to be BGRA to make it clearer as Mark Thompson's suggestion.
V2: Add P010 format support else will introduce HEVC 10bit encoding regression.
Thanks for LinJie's discovery.
