Allow setting terminal cursor for screen readers and IME preview using ui_adaptor

[Qrox]

Summary

Infrastructure "Allow setting terminal cursor for screen readers and IME preview using ui_adaptor"

Purpose of change

The ncurses cursor is used by screen readers and used as the position for IME preview, but it is transient -- any output will change its position, making the code prone to regression when new code is added. Contributes to #39638.

Describe the solution

Set the desired final cursor via ui_adaptor, which automatically sets the cursor to the desired position once all UIs finish drawing.

Migrate existing UIs that set the cursor to the new system.

Finally, place cursor at the highlighted line in the player display (@) menu to demonstrate the flexibility of the system. disable_cursor() and set_cursor() are used to place the cursor at the correct line without having the output code of the non-active UIs interfere with the cursor.

Describe alternatives you've considered

A on_out_of_scope solution might work too, but some drawing code spans several functions, which will make a scope-based solution complicated.

Testing

Tested all affected UIs on the ncurses build. The IME preview was shown at the desired cursor position, so screen readers should also work in these UIs.

Also tested all affected UIs on the tiles build, and the UIs worked as before. Tested #45951 and there was no regression.

Additional context

This should make it somewhat easier to add screen reader support to the remaining menus in #39638.
