Add batterysipper type check in PowerUsageFeatureProvider

This cl adds isTypeSystem to PowerUsageFeatureProvider and
changes isTypeService. After this cl, the following items will
be moved to advanced battery page:
1. Calendar Storage(Move to System)
2. MediaServer(Move to System)

Create this check in FeatureProvider to make sure this check
is flexible in different cases. Also refactor the PowerUsageSummary
to use same test fragment
