  Log Message:
  -----------
  [WebCodecs] H264AnnexBBufferToCMSampleBuffer is not always computing the right AVC buffer size
https://bugs.webkit.org/show_bug.cgi?id=247069
rdar://problem/101593041

Reviewed by Eric Carlson.

Computation of the AVC buffer was a pure translation of the AnnexB buffer size.
This is not always the case, this patch is adding a precise computation to make sure we do not chop some data.
