feat: set active selections by defined name input

[kenny-not-dead]

partial #5979

Excel allows you to enter a range through this input. I think this is a good starting point for implementing this input's functionality.

In the future, I think it might be possible to add the display of defined names and their assignments.

Is this PR still relevant or can it be closed?

team?

Sorry for the slow response. We've been focused on resolving some collaboration issues :)

The PR works well, but the viewport currently fails to scroll to the active selection. This is inconsistent with Excel and undermines the utility of the feature. Could you add logic to ensure the selection scrolls into view?

@jikkai
Could you please specify the scrolling behavior in more detail? Maybe you can make a short video?

[kenny-not-dead]

No matter how hard I tried to define the required behavior, I couldn't figure out what exactly should happen in which cases. In Libre, it works the same way as in PR. Therefore, I would still be grateful for a demonstration of what needs to be added within the video, or a more detailed description of the flow.
