parseSequenceHeaderOBU should return a AV1CodecConfigurationRecord

Reviewed by Youenn Fablet.
Replace ParsedSequenceHeaderParameters with AV1CodecConfigurationRecord
Amend AV1CodecConfigurationRecord to store video dimensions
Have parseAV1DecoderConfigurationRecord take a span and use a BitReader instead
of a JSC::DataView
This avoids two memory allocations.
Amend parseSequenceHeaderOBU to fully decode the Sequence Header OBU and
retrieved the full colour profile when possible.
We'll use this method in a future change to create a VideoInfo structure
where full colour profile is required.
