We should always append sample by using `AppendSample()` to assert whether a sample is valid, so making `mSamples` private can prevent a direct usage of the nsTarry's `AppendElement()`.
Also provide a method to return non-const mSamples which is only used for the move semantics.

We don't want to have a sample with invalid time, duration, end time or end timecode, so add a diagnostic assertion to check. And will handle invalid sample for demuxers in next patch.

Mostly-mechanical additions:
- Log constructions&destructions, usually by just inheriting from
DecoderDoctorLifeLogger, otherwise with explicit log commands (for internal
classes for which DecoderDoctorTraits can't be specialized),
- Log links between most objects, e.g.: Media element -> decoder -> state
machine -> reader -> demuxer -> resource, etc.
And logging some important properties and events (JS events, duration change,
frames being decoded, etc.)
More will be added later on, from just converting MOZ_LOGs, and as needed.

The only actual code use in MediaSourceDemuxer can trivially be folded into
its caller GetNumberTracks in the same class.

In case of successful initialization, there could still be some warning about
a recoverable error. To carry more information about this potential warning,
the resolve-value type of the promise is changed from nsresult to MediaResult.
Existing code doesn't need to be changed:
- In Resolve() calls, the stored MediaResult can implicitly be constructed from
an nsresult -- always NS_OK at the moment anyway.
- In following Then(), the promise's MediaResult can implicitly be converted to
an nsresult.
Future patches will modify some of the Resolve's and Then's, to forward warning
details to some Decoder Doctor object...

Thanks to the previous patch, MediaDataDemuxer::Seek and
SkipToNextRandomAccessPoint (and all overrides in derived demuxers) can now
take their TimeUnit parameter by const&.

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.
