    gimarshallingtests: Add marshalling tests for virtual functions with inout parameters
    
    Virtual functions may use input/output parameters but this is not currently
    well handled by gjs, so adding test cases to gobject-introspection to verify
    that virtual functions correctly receive valid input values and can return
    them.
