Add DeclareOpInterfaceFunctions to enable specifying whether OpInterfaceMethods for an OpInterface should be generated automatically. This avoids needing to declare the extra methods, while also allowing adding function declaration by way of trait/inheritance. Most of this change is mechanical/extracting classes to be reusable.
