Add automatic tiling options when moving an embedded Window

[DragonMaster14545]

Describe the project you are working on

Im currently changing a lot of my menus to use windows, because that just feels better imo

Describe the problem or limitation you are having in your project

Its often annoying to manually resize and move the windows

Describe the feature / enhancement and how it helps to overcome the problem or limitation

It would be really cool if godot allowed automatic window resizing like windows does when you drag a window to the top, it give you options to split the screen in half, in three parts and so on (This thing)

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Basically display a menu similar to the one in windows, when the window is moved to the top of the screen

If this enhancement will not be used often, can it be worked around with a few lines of script?

No, I have not found an easy way to do this

Is there a reason why this should be core and not an add-on in the asset library?

This is a qol feature for built in windows that should not require an extra addon from the asset library
