avcodec/vdpau_hevc: Pass sps and pps range extension flags to VDPAU
Pass SPS, PPS range extensions to VDPAU layer via
VdpPictureInfoHEVC444. Added VdpPictureInfoHEVC444 struct to
VdpPictureInfo union to populate the range extension params. Mapped
FF_PROFILE_HEVC_REXT to VDP_DECODER_PROFILE_HEVC_MAIN_444.
