GDScript 2.0: Enum values can't be compared to variable integers

[vntxx]

Godot version

v4.0.dev.calinou [bfc14a6]

System information

Windows 10

Issue description

Once comparing an enum against an integer in code it will be marked as an error. I am assuming that this is a regression since it did work in GDScript 1.0 (Godot 3.x). Note that this behaviour occurs regardless of the enum value having an integer value assigned to it.

Steps to reproduce

Compare an enum value against an integer inside a GDScript file (see below)

Minimal reproduction project

Create a new GDScript file inside the engine and paste the following:

enum SomeEnum {
	VALUE = 1
}

func function():
	if 0 == SomeEnum.VALUE:
		pass
	
	const integer_const: int = 1
	if integer_const == SomeEnum.VALUE:
		pass
	
	var integer_var: int = 1
	if integer_var == SomeEnum.VALUE: # Error
		pass

Seems closely related to #49278 and fix for it #49449. .
Also probably #43035

Reopening as the fix in 6207708 was reverted due to a regression.
