[FEATURE] Enums in Hscript

[lemz1]

DESCRIPTION

This pr aims to make it possible to import enums.
The macro creates "wrappers" around the actual enum.

EXPLANATION

For example funkin.ui.NavControls:
We create a class polymod.enums.funkin.ui.NavControls.
This class has all fields of funkin.ui.NavControls, and treats them as regular variables and functions, which call the respective fields from the actual funkin.ui.NavControls enum.
We then create an alias for funkin.ui.NavControls and make it point to polymod.enums.funkin.ui.NavControls.

EXAMPLES

import funkin.play.song.Song;
import funkin.ui.NavControls;

class ExampleSong extends Song
{
	function new()
	{
		super('exampleSong');
		
		trace(NavControls.Columns(5)); // Columns(5)
		trace(NavControls.Rows(5)); // Rows(5)
		trace(NavControls.Both); // Both

		trace(NavControls.Rows(5) == NavControls.Rows(3)); // false
		trace(NavControls.Rows(5) == NavControls.Rows(5)); // true
	}
}

TODO

• Make all enums accessible
• Make switch statements work
