power: supply: support charge_types in extensions

Similar to charge_behaviour, charge_types is an enum option where
reading the property shows the supported values, with the active value
surrounded by brackets. To be able to use it with a power_supply
extension a bitmask with the supported charge_Types values has to be
added to power_supply_ext.
