Since we can determine which browsing context contains an active media session via `MediaSessionController`, we should notify that context directly in order to access correct media session. Especially after we enable Fission, browsing contexts could exist in different processes, so choosing the right context to notify is really important.

Create a class `MediaSessionController` which is used to track all alive media sessions within a tab and store their metadata which could be used to show on the virtual media control interface. That class would also be responsible to select an active media session with in a tab.

As we will have a use to send media metadata from the content process to the chrome process in the future, we would like to send only `title`, `artist`, `album` and `artwork` without having anyother member variables and methods which are useless for our use case, such as `nsIGlobalObject`.
Therefore, create a base class which contains what we need, and let `MediaMetadata` inherit from that class.

Create dummy implementations for the MediaSession interfaces. The files
are generated by running `./mach webidl-example` with necessary changes
to make it buildable.
The internal implementations are blank in this patch. They will be done
in the following patches.
Due to some spec issues, the final implementations only support some
basic operations like "play" and "pause".
