Revert "Audio: Add Pause/Resume in AMR-WB tunnel recording"

This reverts commit e51f3b1dd8b8b2668af3c467a330b18714d29966.

There's no mSource->stop() in MPEG4Writer::Track::pause(),
so no need to add this limitation here.

AudioTrack: Handle track invalidate on wait for stream done

If a track invalidate is called while waiting for a stream done,
AudioCallback handler is notified with event EVENT_STREAM_END.
This might cause substantial data loss for offload playback. Try to
recreate the track if needed.

- Perform HFR scaling with mp4 timescale parameter instead of
  recalculating timestamps

libstagefright: HSR: Check if HSR enabled, use HFR value for HSR

- HSR is high speed recording hint from camera app, if this is set
  use frame rate set in HFR as normal encoder frame rate.
- HSR hint also indicates that this is not HFR feature and treat
  this encoding as normal encoding

stagefright: Correct total duration of HFR clips

HFR leverages the mp4 track timescale parameter which is not
considered when calculating total clip duration. This makes tracks
report the correct duration so that total clip duration is computed
correctly.
