Implement DeviceOrientationClientAndroid

This class acts simply as a proxy to the real or mock client, which is owned by
the WebView. DEVICE_ORIENTATION is eabled on Android, so we must implement the
client before we pull in http://trac.webkit.org/changeset/64356, which calls
DeviceOrientationClient::setController() from the Page constructor.
