Zhong Li 52ed83fa1a lavc/qsvdec: expose frame pic_type and key_frame 
Currently pict_type and key_frame are unset.
Add an extra param to fetch the picture type from qsv decoder

The judgement “key frame is equal to IDR frame” only suitable for H264.
For HEVC, all IRAP frames are key frames, and other codecs have no IDR
frame.
