Subject: [PATCH] [Media ML] Update
 MediaSessionManager#getActiveSessionsForUser

In order to make getActiveSessionsForUser, we need to remove
@UnsupportedAppUsage first.
Following UnsupportedAppUsage removal policy by adding
publicAlternatives to be gathered by internal tool and published
on the Android Developers site.
