Improved user callbacks on SystemService:

* Renamed:

  onStartUser() -> onUserStarting()
  onStopUser() -> onUserStopping()
  onSwitchUser() -> onUserSwitching()
  onUnlockUser() -> onUserUnlocking()
  onCleanupUser() -> onUserStopped()
  isSupportedUser() -> isUserSupported()

* Added:

  onUserUnlocked()

Tested on automotive, which uses the callbacks to dump user metrics:

$ adb shell dumpsys car_service --user-metrics
adb shell dumpsys car_service --user-metrics
* User Metrics *
