Add picture-in-picture camera preview to the editor when a Camera2D node is selected

Describe the project you are working on

I'm working on a 2D animation project.

Describe the problem or limitation you are having in your project

The 3D viewport allows you to split the screen and preview the camera. This allows you to immediately see the result of camera animation, which makes it very convenient for working on cinematic scenes. 2D viewport and camera2D do not have this feature.

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

Add the ability to preview a 2D camera in the viewport. And implement this proposal #7642

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

Exactly the same as in 3D, excluding 3D-specific things.

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

I think this is hardly possible.

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

This function is already in 3D, as part of the core. I think it should be the same with 2D.

Make a split screen like in a 3D editor and add the ability to preview a 2D camera.

These are separate items that can be implemented independently from each other. Please open a separate proposal for each, so that implementation progress can be tracked more easily.

Done. Linked it in the proposal.

This project implements a more user friendly option in my opintion:

Might be worth integrating into Godot itself
