Add av1 to MediaSource.isTypeSupported

When av1 video playback is enabled, declare it as supported in the webm container in MediaSource.IsTypeSupported.

Also support special mime types of the form video/webm; codecs=vp9.experimental.<git-commit-id> so test sites can verify playback support of particular encodings while the av1 bitstream is under development.
