Add function to rotate/transpose all windows

[pranshu sharma]

An useful for function for C-x w map is to add a function to rotate
windows.

What I mean by this is basiclly rebuilt the window tree, but do vertical
split where a horizonal, and vice versa.

For example if we rotate the the frame with the windows A B C:
- | A | B |       | A |   |
- |-------|   - > |---| C |
- |   C   |       | B |   |

I think this is extremly useful, as sometimes for example I open a
window with a horizontal split, and the lines are rather long, then I
have to manually toggle the window split to vertical.

An example of this:

The code in this has the following limitations:
- Does not work in emacs 29.1
- No good way to transpose only specific parts of window tree
