Issue description

When porting https://github.com/jamie-pate/godot-code-coverage to godot4 I found that ResourceLoader.get_dependencies("res://script.gd") now returns empty for all scripts.

In godot3 the dependencies were tracked in gdscript_parser.cpp, but now there is just a TODO comment in gdscript_parser.h:

	const List<String> get_dependencies() const {
		// TODO: Keep track of deps.
		return List<String>();
	}

Workaround: I guess I'll have to find preload and load using regex which won't work for dynamic loading

Steps to reproduce

• Create a script "some_script.gd" with a preload("res://other_script.gd") statement
• call var deps = ResourceLoader.get_dependencies("res://some_script.gd").
  The deps should have one member "res://other_script.gd"

Yes, this is something that slipped my mind at the time and nobody else noticed, I guess. I didn't forget about it, just didn't come to it yet. But I'll put this on the top of my list, since it's an actually important feature.

Reopening as #90860 caused regressions and was reverted for 4.3.
