audioserver: add automated audio power logging
We utilize the wakelock and batterystat logic to measure
by app the power used during audio playback.
This is integrated into audioserver to allow close tracking
of apps in and out of suspend.
This is default disabled for now. Before trying, use
$ adb shell setenforce 0
$ adb shell setprop persist.audio.power_stats.enabled true
$ adb shell aflags enable com.android.media.audioserver.power_stats true
Flag: com.android.media.audioserver.power_stats
Test: atest powerstats_collector_tests
Test: atest audio_powerstats_benchmark
Test: audio_powerstatscollector_benchmark
Test: atest audio_token_benchmark
