Calling AlarmManager to know the state of the permission, which is now
the source of truth, as the logic deciding the state of the permission
may change.
Also killing the app when the permission changes to denied, this avoids
the app maintaining stale state about this permission.
Test: make -j RunSettingsRoboTests
atest SettingsUnitTests:AppStateAlarmsAndRemindersBridgeTest
Manually: Toggle the state of an app to "Not allowed" and check the logs
for activity manager kill messages.
