The package name is useful for permission validation. Currently, package name is required when starting external vibration so that the vibrator service can verify if the app has the permission to start vibration. Bug: 175595599 Test: SoundPool tests in cts Test: play audio-coupled-haptic file using SoundPool. Change-Id: Ibfe414063a303118a5bb393d65ea5dc2323bf722 Merged-In: Ibfe414063a303118a5bb393d65ea5dc2323bf722 (cherry picked from commit de9005bab1751e23342bbc9f0f51213eea8885af)
