Expose NRI#rejectCause as Public
Expose the existing rejectCause() API as public, which
is useful in situations where a caller was unable to
pre-register for TelephonyCallback#onRegistrationFailed().
The reject cause also indicates a terminal failure, which is
easy to distinguish if a caller is not interested in
intermediate results during a network selection procedure.
