healthd: break link between BatteryMonitor and BatteryPropertiesRegistrar
Make it easier to later separate out binder-related code. Add helper functions healthd_battery_update(), healthd_get_property() to allow these operations without needing references to the BatteryMonitor object. Change-Id: Ie584bf53e5178ce0a098d0d940d6c311fdff62d4
