C# Enums don't match globalscope

**Your Godot version:** 3.3.3 (stable)

**Issue description:** I was trying to use Input.IsKeyPressed(KeyList ENUM) in my C# code and the enum list in the docs completely doesn't match how to call it in C#. For example, it lists KEY_D as the "D" key but you actually invoke it as KeyList.D. I'd find that mildly annoying and not report worthy, until I had to use shift and control. They do not seem to be KeyList.SHIFT, KeyList.KEY_SHIFT or literally anything else I could think of. I tried looking at the Godot repo and I cannot for the life of me find where its defined. This is way too opaque and it sucks :(
