Register non-GDScript classes as global classes

Describe the problem or limitation you are having in your project

Long story short I had to use Kaitai Struct in my project and have chosen C#, which means GDScript and C# interopt. I found out that I cannot refer to my wrapper class(for tying KS into the Godot-land) by its class name. This forced me to use load()/preload(). I then discover that, from GDScript, Godot does not know about any methods I have defined in my C# script. This means no autocompletion from the GDScript side at all. This makes GDScript/non-GDScript language interopt a huge pain.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Allowing GDScript codes to refer to non-GDScript classes by name obviously makes using multiple languages a lot smoother. for example, you can define a C# class:

public class MyNode : Node

And refer to them by name in GDScript without having to use load() or preload(), with full autocompletions

var node := MyNode.new()

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

I don't know how Godot's internals work, but since there are ways to register classes in C++(ClassDB), that could probably be used to register non-GDScript classes just like with C++.

If this enhancement will not be used often, can it be worked around with a few lines of script?

As far as I know, there are no way to register non-GDScript classes from any language other than C++. Even with C++, I don't even know if it's possible to scan C# classes.

Is there a reason why this should be core and not an add-on in the asset library?

Doesn't godotengine/godot#48201 address this (according to godotengine/godot#40147 (comment))? If so, I think this is a duplicate of #18.

Not sure about that, but I'll subscribe just in case.
