Support to customize launching position for every debug instance

[kdada]

Change run/window_placement/rect_custom_position to an array to support specify position of every debug instance.

Now I can debug multiplayer instances without Run & moving window & moving window & moving window & moving window.

Thanks for your information.

I read the proposal and #64913. #64913 is different from this PR. This PR only controls the positions of windows and do not touch on debug identity.

I also reviewed #64913 and left some comments.

@Calinou Could this pr be merged?

@clayjohn Could you also take a look of this PR?

Fixed conflicts

The code looks fine to me, but I have a feeling this change will break compatibility for projects that are already using this ProjectSetting. @bruvzg @akien-mga Are we okay with breaking compatibility here?

[bruvzg]

It's an editor setting, so won't break actual projects and probably ok.

I think these kind of settings should go through a proper "Run Configuration" widget (godotengine/godot-proposals#522 , godotengine/godot-proposals#522 (comment)), likely using project metadata instead of editor settings.

It seems the implementation of #65753 is more general. Will Window Placement be deprecated in the future?

It makes sense to move it to wherever we store the run configuration

But it doesn't have explicit window placement options, right?
I think it would make most sense to use a combination of the two.
For most scenarios where you want to move the windows of multiple instances, we are talking about a multiplayer game with multiple clients/servers. For that use-case passing parameters in addition to the window placements would be great, because you can specify which instance would be responsible for what role.
