    codegen: Generated SimpleType structs don't have a type id
    
    Set "CCode.has_type_id" in CCodeStructModule.generate_struct_declaration()
    like in GTypeModule.visit_struct() for SimpleType structs which might be
    executed too late.
    
    In addition to 2e798fc3f8e9af25a4c231c2561894d9f0a0be50
