MediaDecoder previously had 3 states within GetSeekable(), media is either
seekable, seekable but not supported by transport, or not seekable. Due to
changes to make cueless webms playable, a 4th option is needed: a file that is
not fully seekable, but may support seeking from the transport, such as these
webms, should only be seekable in the buffered range.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

A MediaDataDemuxer is now not to resolve the init promise until it has all the metadata.
Except MediaSource, all demuxers would be doing blocking read to scan for the metadata, and having partial metadata would be an error.
For MediaSource, we pass the NotifyDataArrived message which will cause the MediaSourceDemuxer to re-attempt to search for the metadata.
When used within MediaSource's TrackBuffersManager, a demuxer will never be created until we have received a complete init segment (this task is performed by the various ContainerParsers)
This is used by the MediaFormatReader to dermine if buffering heuristics should
be used.
