WebCoreDecompressionSession should be using asynchronous decoding
https://bugs.webkit.org/show_bug.cgi?id=292362
rdar://148016051
Reviewed by Youenn Fablet.
Make WebCoreDecompressionSession use a VTDecompressionSession in asynchronous
mode.
Also, allows it to handle one to many CMSampleBuffer -> decompressed frame.
while this isn't a usual scenario, it is possible for the SourceBufferParserWebM
to pack multiple CMSampleBuffer into one, and currently it was only ever
returning
the first frame.
No change in observable behaviour, covered by existing tests.
