PDMFactory will automatically load and initialize the required frameworks upon first use.
Also fix constness of some methods.

Pass declared-but-yet-undefined DecoderDoctorDiagnostics pointer to various
routines that contribute to deciding if a media format can be played, and
those that create decoders.
Points where a DecoderDoctorDiagnostics can be injected are currently marked
with "/* DecoderDoctorDiagnostics* */ nullptr", and some will be used in
following patches.

When running gtest, none of the prefs actually exist, so we end up having most PDMs disabled.

We now use an index of samples made of block of samples delimited by keyframes. The search is performed using a binary search. This allows to quickly find which blocks are found within the media cache.
On a 8 core mac pro, this leads to a 67% improvement on CPU time spent playing a long MP4 video (from 112s CPU to 45s CPU)
The optimisation is only possible if all mp4 data chunks are continuous (which they almost always are)
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.

The LayersBackend can be defined at construction time, however if a parent MediaDecoder exists, the value will be overwritten by the MediaDecoderOwner value.

The PDMFactory will run more accurate checks based on the TrackInfo object and will fail to create a decoder if the type is unsupported. So use that instead

In MP4TrackDemuxer constructor, getting the track info and indices could potentially fail, triggering crashing assertions.
The fallible work is now done before calling the constructor, and if it fails a nullptr is returned, which is correctly handled in MediaFormatReader.
Also reordered some MP4TrackDemuxer members for more natural construction.
