avcodec/cbs_vp8: Add support for VP8 codec bitstream
This commit adds support for VP8 bitstream read methods to the cbs codec. This enables the trace_headers bitstream filter to support VP8, in addition to AV1, H.264, H.265, and VP9. This can be useful for debugging VP8 stream issues. The CBS VP8 implements a simple VP8 boolean decoder using GetBitContext to read the bitstream. Only the read methods `read_unit` and `split_fragment` are implemented. The write methods `write_unit` and `assemble_fragment` return the error code AVERROR_PATCHWELCOME. This is because CBS VP8 write is unlikely to be used by any applications at the moment. The write methods can be added later if there is a real need for them.
