Add package name when initializing SoundPool.

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)
