audioflinger: add setCallerName() to AudioTrack

And also to AudioRecord.
Then log the callerName using MediaMetrics from the destructor.

This can be used to tell whether AAudio or OpenSL ES
or Java created the object.

Bug: 154543374
Test: adb shell dumpsys media.metrics --clear
Test: Run an app that uses audio.
Test: adb shell dumpsys media.metrics
Test: Look for "callerName" in the dump.
