VPL GPU runtime open source has already supported it.

@FurongZhang The link provided by you is for encoding only, we can't fetch hdr metadata via MFX_EXTBUFF_MASTERING_DISPLAY_COLOUR_VOLUME and MFX_EXTBUFF_CONTENT_LIGHT_LEVEL_INFO for av1 decoding. This works for hevc decoding (see https://github.com/oneapi-src/oneVPL-intel-gpu/blob/main/_studio/mfx_lib/decode/h265/src/mfx_h265_dec_decode.cpp)

The recent commit 0d0ba3c should have fix it. Then this PR for ffmpeg can continue.
