This is not the cleanest approach, but ensures identical behavior with the OggReader when it comes to firing loadedmetadata event and handling the change of seekability.
A more universal solution could be considered involving the MediaFormatReader and changing the MediaDataDemuxer API, of interest would be adding support for a new event fired whenever we have a change of content or metadata (useful with MSE or recorded webm of a WebRTC session

Implemented by short-circuiting calls to RequestVideoData in MDSM so no
frames are decoded. Resuming playback when video moves to foreground by
using the SeekTask/SeekJob/Seek in MDSM with result of GetMediaTime().
Special consideration is made to only seek the video part of Seek() to
remove an audible glitch in the audio playback when the video becomes
visible again.

change MediaDecoder::mIsVisible to be a Canonical<bool> and plumb through to
the MediaDecoderStateMachine. This will be used to trigger suspending the
decoding of video frames.

MediaDecoderStateMachine's EnqueueFIrstFrameLoadedEvent would previously call
into MediaDecoderReader to update MDR's buffered ranges and enqueue the frame
loaded event. This commit aims to instead have the buffered update take place,
and only afterwards enqueue the event. This should remove the possibility that
the event will be fired and handled before the update of the buffered ranges has
taken place.

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.
