  [iOS] iOS AV1 HW decoder requires to get the OBU header in its av1C

Reviewed by Jean-Yves Avenard.

iOS AV1 decoder needs the header OBU in its av1C to properly initialize itself.
We update getSequenceHeaderOBU to return bothe the full OBU and the obu data.
We then update computeAV1InputFormat to append the full OBU to the av1C data.

Manually tested using https://webrtc.github.io/samples/src/content/peerconnection/change-codecs/ on iPhone 15 Pro.
