vd_lavc: use avcodec_fill_hw_frames_parameters() API

This removes the need for codec- and API-specific knowledge in the
libavcodec hardware acceleration API user. For mpv, this removes the
need for vd_lavc_hwdec.pixfmt_map and a few other things. (For now, we
still keep the "old" parts for the sake of supporting older Libav, and
FFgarbage.)
