Add skip_frame support to qsvenc. Use per-frame metadata "qsv_skip_frame" to control it. skip_frame option defines the behavior of qsv_skip_frame. no_skip: Frame skipping is disabled. insert_dummy: Encoder inserts into bitstream frame where all macroblocks are encoded as skipped. insert_nothing: Similar to insert_dummy, but encoder inserts nothing. The skipped frames are still used in brc. For example, gop still include skipped frames, and the frames after skipped frames will be larger in size. brc_only: skip_frame metadata indicates the number of missed frames before the current frame.
