Set media router group id to sync cast status

Using media router group id, Settings can sync cast status with
Settings.
If Settings begins/stops cast (mirrorring), CastTile can know that and
Settings also knows when CastTile begins cast.

Please refer ag/7669852 to how router group id can be used to
synchronize cast status.
