libavcodec/qsvenc: Add intra refresh to hevc_qsv and add new intra refresh parameter
Add intra refresh support to hevc_qsv as well.
Add an new intra refresh type: "horizontal", and an new param
ref_cycle_dist. This param specify the distance between the
beginnings of the intra-refresh cycles in frames.
