Change how _make_visible is called involving _edit and _handles

[migmoog]

I've been making my own editor plugin that's essentially an alternative script editor. I've been trying to implement a "pop out window" feature similar to the default script editor, but I'm finding some issues with how the editor plugin system is handling it.

I've overridden the _handles and _edit methods of the EditorPlugin, and when my plugin is docked it feels great

func _handles(object: Object) -> bool:
	return object is Script

func _edit(object: Object):
	if object == null:
		return
	
    # code that opens the file in my plugin

However on the implementation of the pop out window, I'm finding this really annoying irk when opening a file in the editor. Because calls to _edit are preceded by a call to the prior main screen's _make_visible(false), it changes the main screen, ruining the flow of the editing experience.

The default script editor doesn't have this problem because it cheats while it's floating.

I'm not entirely sure on what would be a good approach, but it would have to be backwards compatible. Maybe another virtual method?

func _should_switch_main_screen() -> bool:
   return is_floating()
