Formalize Connection CallQuality report APIs

Promote Connection#EVENT_CALL_QUALITY_REPORT as well as
Connection#EXTRA_CALL_QUALITY_REPORT into proper system APIs. These are
used by Telephony to send the call quality report from Telephony over to
Telecom which is retreived by CallDiagnosticService.
