Add new interface in CarrierPrivilegesCallback to notify the registrants
that carrier service for current user has changed.
Reshape the parameters of onCarrierPrivilegesChanged callback with
both Set instead of List/Array.
CarrierPrivilegesListener is deprecated. Once all clients have migrated
to CarrierPrivilegesCallback, it will be throughly cleaned up.
