Removes SmartActions from Rankings before marshal

To allow us to put RankingMap in ashmem when NotificationRankingUpdates
are sent to NotificationListeners, we move the SmartActions that
may be contained in each Ranking object into a separate list, Parcel
them and send them across binder normally, and store the rest of the
RankingMap in ashmem. Then, when we unparcel the
NotificationRankingUpdate, we re-merge the Actions into the RankingMap.
