[CR] Interface: NewCharacter - Add responsive screen behavior for small terminal sizes

Summary

SUMMARY: Interface "NewCharacter - Add responsive screen behavior for small terminal sizes"

Purpose of change

@ZhilkinSerg already paved the way in #45342.
This changes NewCharacter-Menu to be more responsive, especially with really small screens (terminal size of 80x25).
You won't see any difference on larger screens. Much like modern websites handle different devices and screen sizes.
It's not perfect yet. But it's a start, and it's definitely an improvement.

Testing

• Compiled using microsoft visual studio 2019.
• Checked that everything is working as expected.

Too bad AppVeyor isn't up and running. Really don't wanna mess up anything.

If you're using VS, I'd be least worried about appveyor not working, it's also testing VS. The other tests are more important because they aren't testing similarly to you.
