Ringtone: Add support for selection of phone ringtone for SIM-2.

-Issue: "The process android.process.media has stopped" pop up is
 displayed when ringtone for SIM-2 is selected.
-Rootcause: There is no type and URI defined for SIM-2 ringtone
 in the RingtoneManager. This is leading to SQl exception when
 executing a selection query.
-Fix: Add URIs for the SIM-2 and SIM-3 ringtones. Define
 interfaces to return them to app side based on subscription ID.
