Implement Floating Script Editor Window

[SirQuartz]

I've been working on a solution to make the script editor a floating window. This addresses godotengine/godot-proposals#28

Here's a working prototype:

Floating.Script.Window.mp4

It's not perfect, still has some bugs, but it works quite well nevertheless.

Hi @SirQuartz, you may be happy to know that I'm already working to that as part of the GSOC'22 (link to the project).
I already start working to it here: https://github.com/trollodel/godot/tree/gsoc_2022_multiwindow.

Oh wow, I wasn't even aware of that, that looks way better than whatever I was trying to do!

I will check @trollodel implementation. How ever, yours or @trollodel should allow to have the code window and a viewport at the same time to allow multi monitor

@trollodel Niceeee

BTW. The floting window doens't allow for F1 while focus

Thanks @jcostello, but please don't go off-topic talking about my work, as this is someone else's PR.
I'll open a draft PR soon to allow discussion there.
EDIT: Here's the PR: #62378

I see no reason to continue working on this since @trollodel was already working on this and has a better solution.
