multiple users support for carrier wifi provisioning

1. Add a new intent to wake up carrier provisioning apps to handle
the refreshing request on user switching.
2. When user switching happens, trigger app check provisioning status;
3. Broadcast 'ACTION_NETWORK_SETTINGS_RESET' to current user only to
align with frameworks behavior;

Bug: 156751190
Test: manual test, both SIM card changing and 'reset wifi' in multiple
users case.
