Migrate TelephonyManagerShimImpl to new CPCallback interface

CarrierPrivilegesListener is renamed to CarrierPrivilegesCallback,
with new API introduced to support carrier service change and
better API surface.

This CL introduces minimum change to remove dependency on the deprecated
interface. A follow up CL will refactor thoroughly with the new
carrier service change API.
