Move MediaController.java upstream to Chromium repository.

MediaController.java is used by the android cast code which upstreamed from the private Chrome for Android repository.
It derives from open source Android source code,
specifically from one of the Android supportv4 samples, and has been
in the downstream repository for some time.

See the README.chromium file for more details.
