Generic types and methods constrained to enums are incorrectly generated

[Dooomsickle]

Description

When attempting to use a method or class with a type parameter T that's constrained to an enum (in Il2CppInterop's case, generated as where T : Il2CppSystem.Enum) you are unable to do so as IL2CPP enums are generated as managed ones, which fail the type check.

Potential Fix

Remap all Il2CppSystem.Enum generic constraints to System.Enum
