Allow stopping user to access AppWidgetService API

We now have isUserRunning && isUserKeyUnlockedisUserUnlocked instead of
having isUserUnlockingOrUnlocked. The difference is
we now allow stopping unlocked user to access the API.

Testing:
Write a simple widget which keep calling AppWidgetManager API in a loop.

1. In non-FBE mode, place the widget to launcher.
   Turn off work mode. No crash is observed.
2. Repeat 1 in FBE mode with separated work challenge.
3. Repeat 1 in FBE mode with no separated work challenge
4. Repeat 2 and reboot the device. Unlock work profile, widget is shown
5. Repeat 3, reboot device, widget is shown after rebot
