avcodec/videotoolbox: pass through hevc param changes to the decoder

Browse Source 
This includes the SEI_PREFIX/SEI_SUFFIX NALUs, which can contain
updates like HEVC_SEI_TYPE_ACTIVE_PARAMETER_SETS. Previously, hevc
samples with this SEI present would not playback correctly.

See for example https://github.com/lhc70000/iina/issues/1123
