Update RadioTuner APIs for AIDL HAL migration

Browse Source 
APIs in RadioTuner were updated to adopt broadcast radio HAL
migration to AIDL:
- New APIs seek and onConfigFlagUpdated were added since corresponding
  new interface methods were introduced in broadcast radio AIDL HAL.
- APIs only used in HIDL 1.x broadcast radio HAL were deprecated.
- The use of deprecated onError callback was replaced by onTuneFailed
  in tune, seek, scan and step APIs. Corresponding result types were
  also defined in RadioTuner.
- Multi-user behaviors for RadioTuner APIs were specified.
Meanwhile, a new DAB radio primary identifier was added, which was
extended to 44 bits to support Digital Multimedia Broadcasting (DMB)
radio.
The integer annotations in radio APIs were also improved.
