[mce-qt] Add battery related items. Fixes JB#44019

Implements new Qt classes / QML items for tracking:

MceBatteryLevel:  Current charge percentage
MceBatteryStatus: Current status as Empty|Low|Ok|Full
MceCableState:    Whether charger cable is connected
MceChargerState:  Whether battery is getting charged
McePowerSaveMode: Whether PowerSaveMode is active
