[FFmpeg-devel] [PATCH v2] avcodec/cbs_vp8: Add support for VP8 codec bitstream READ methods

This commit adds VP8 into cbs supported codec list, and enables the `trace_headers` bitstream filters to support VP8, besides existing AV1, H.264, H.265 and VP9. It can be useful to debug VP8 stream issues. Only the READ methods `read_unit` and `split_fragment` are implemented, the WRITE methods `
