When sending a MediaItem to a MediaSession with a Media3 MediaController important information is removed for privacy reason. To look up the fully populated MediaItem the mediaId is used as a key. Hence having the mediaId marhalled to the JSON representation that is sent to a Cast device enables app developers to use the same look up facilities. #minor-release PiperOrigin-RevId: 420022868
