qom/object.c: introduce OBJECT_CLASS_PROPERTY_SCALAR_GETTER(type) macro
This macro will be used to generate the boilerplate property_class_get_type_ptr() QOM get function for the specified scalar type. Note that since the macro is currently unused, the object_class_prop_ptr() helper function is temporarily marked as __attribute__((unused)) to allow compilation to succeed.
