MediaMetrics: Implement audio power usage metrics

- Trigger audio power usage logging when
   1. endAudioIntervalGroup event for track/record
   2. setMode to NORMAL for telephony
- Aggregate audio usage by type and device
- Send audiousage data every 24hrs by default, using property
  persist.media.audio_power_metrics.interval_hr to config the interval
- Add property persist.media.audio_power_metrics.disable to disable
  audio power metrics
