[FEATURE]: Ability to attach scripts to nodes

[TheColorRed]

I saw it in another gdextension library (J.E.N.O.V.A. for c++) that you can attach scripts to nodes instead of creating a whole new node, as it works just like you would attach a GDScript. This would be nice if that was supported.

This is partially supported through script instances, see godot::obj::script.

That said, it's not the primary workflow, and I personally won't be able to maintain scripting next to all the other priorities. In the past @TitanNano has helped a lot (and is the reason why so much exists at all right now 🙂). Would you be interested in working on these parts?

There is also godot-rust-script that builds on gdext and allows for creating scripts in Rust.

@TheColorRed you can add scripts to nodes. it just involves a whole process of making a ScriptLanguage, then you need to make a Script class for your language which creates ScriptInstances. an the Script also needs ResourceFormatSaver and ResourceFormatLoader (and if you mess up any of these classes the engine can and probally will crash. eg: The ResourceFormatLoader not detecting Script as a valid type so your script gets loaded as a TextFile and immedeatly casuing a nullref and crashing when it cast it to Script)

Closing since this is already possible, and there's godot-rust-script to streamline the process.

For godot-rust itself, I see the focus for now on improving the respective APIs so that users are unblocked in implementing the missing parts, and there's less than can be done wrong. But there's already #970 to track this.
