Add UndoRedo icon

[MewPurPur]

UndoRedo is an Object, but its icon still shows up in some places, so why not?

Looks kind of like refresh icon.

[MewPurPur]

We also have Loop.svg which is a bit similar but not strikingly so.

So I understand how this association could come up.

I personally really associate these little curves at the start of arrows with Undo & Redo, in Godot we don't have any buttons for these things though.

[KoBeWi]

What if the icon only included Undo? I think this one looks fine:

btw there is also EditorUndoRedoManager, maybe you can come up with something as well (undo + manager?)

EDIT:
Seems like we have some rotate icons that look similar.

[MewPurPur]

Yeah, the rotate icons and History.svg are too clashy imo. I'm down with only having Undo as it's the more iconic one, I'm personally keen on these two:

I don't know an awful lot about EditorUndoRedoManager, can't think of much either

[KoBeWi]

The lower one looks ok.
The upper one is like "Back".

I don't know an awful lot about EditorUndoRedoManager, can't think of much either

It's basically a wrapper for UndoRedo that works in scene context.
idk, put a suit on UndoRedo texture and it will look like a manager. Probably.

I think this has closer association with a "history" type of icon, some combination of an arrow and a clock face.

[MewPurPur]

I don't wanna compile Godot just to show how it looks in the editor, but it's not a convoluted icon so I don't see any way it'd look bad at 16x16
