Issue description

Related to #1584, although the introduction of typed dictionaries makes this much more complicated.

TypedArray and TypedDictionary should be able to take enum types that have been registered with VARIANT_ENUM_CAST as the element or key or value type, treating it as an integer with whatever metadata is needed to make the editor show the correct type name in the brackets.

Steps to reproduce

Contrived toy example:

class Foo : public Object {
    GDCLASS(Foo, Object);

protected:
    static void _bind_methods();

public:
    enum Animal {
        CAT,
        DOG,
        HORSE,
    };

    TypedArray<Animal> get_animals_that_should_go_in_a_house() const;
    TypedDictionary<Animal, ArrayMesh> get_animal_meshes() const;
};

VARIANT_ENUM_CAST(Foo::Animal);

Actual project where I am using typed arrays and dictionaries of enum types: https://github.com/BenLubar/godot4-spy-cards-online
(In the actual project, src/dry.h contains a lot of helper macros.)
