Add a type for battery receiver, then in callback client know for
which reason it been invoked:
1. battery level change
2. battery saver state change
3. battery plug state change
So in this CL, we won't update battery tip for battery level change,
then battery tip won't be dismissed by itself.
Also note in onResume() we will manually update battery tip. So if
user stay in battery settings page and close the screen, once he opens
it we will still force update everything.

In PowerUsageBase, it will store battery stats if it has a configuration
change, which will make BatteryStatsLoaderHelper never get the correct
battery stats because it uses Bundle.EMPTY as the bundle message.
This cl:
1. Remove the store action even though it is configuration change.
2. Always use null to get battery stats
3. Always start a battery status check in register()

Before this cl, the battery text in SettingsActivity is one time
update, won't refresh based on real battery status.
This cl elicits BatteryBroadcastReceiver from PowerUsageBase and
make it reusable in both SettingsActivity and battery page.
BatteryBroadcastReceiver will invoke callback if:
1. Battery level changed on integer level(100->99)
2. Battery status has changed(i.e. charging)
