Displaying HD audio indicator for GSM/CDMA calls

Return audio quality information during a voice call along with call
details from RIL. This information is expected to be used to display
HD audio indicator when wide band speech codec is notified.
This feature is necessary to fulfill some carriers requirement.

Test: manual - Checked that HD audio indicator is displayed on UI in
GSM/CDMA calls.
Bug: 30207043
