Address lack of some GameMaker code definitions (e.g. built-in function arguments, return types)

[VladiStep]

Which component should be improved?

Decompiler

Describe your feature suggestion in more detail

There is a "gamemaker.json" definition file for Underanalyzer (code decompiler), but it's relatively small - it lacks a lot of built-in function definitions, like a return value type of draw_get_color() (it should be resolved as color, but it resolves as a number).

So I think the file should contain at least most of the definitions, but there are some differences for different GameMaker versions, so IDK how to do that properly.

(I am not sure if this should be considered as a feature or a bug, probably it's both)

This can be resolved semi-automatically by parsing the GML documentation (it's available for download) and/or the GML editor feather file (it also contains built-in functions and variables definitions)
