qom: Allow optional sugar props
Global properties have an @optional field, which allows to apply a given property to a given type even if one of its subclasses doesn't support it. This is especially used in the compat code when dealing with the "disable-modern" and "disable-legacy" properties and the "virtio-pci" type. Allow object_register_sugar_prop() to set this field as well.
