Add public add/removeOnMediaKeyEventSessionChangedListener

The MediaSessionManager has two system APIs
 - addOnMediaKeyEventSessionChangedListener
 - removeOnMediaKeyEventSessionChangedListener
which listen the media key session updates.

Since the APIs require MEDIA_CONTENT_CONTROL permission,
non-system apps could not use the APIs.

This CL adds an overloaded version of those APIs so that apps with
enabled notification listener can use the functionality.
