lib/types: deprecate functor.wrapped in types.listOf

`functor` is an implementation detail and should not be relied upon, but since its status wasn't clear and it has had some use cases without alternatives, changes are being handled as gracefully as possible. Deprecations within functor:

- `functor.wrapped` is now deprecated for some types and using it will give a warning with migration instructions. It is deprecated for these types:

    - `lib.types.attrsWith`

    - `lib.types.listOf`

      getSubOptions = prefix: elemType.getSubOptions (prefix ++ ["*"]);

      getSubModules = elemType.getSubModules;

      substSubModules = m: listOf (elemType.substSubModules m);

      functor = (defaultFunctor name) // { wrapped = elemType; };

      functor = (elemTypeFunctor name { inherit elemType; }) // {

        type = payload: types.listOf payload.elemType;

      };

      nestedTypes.elemType = elemType;

    };
