Wayland security model does not allow any app to "listen" keystrokes that belong to other windows. So our x11 API-based input helpers are useless with XWayland. More of this, under Wayland ttyxi introduces severe input delay. Steps to reproduce it:

1. install fresh ubuntu 23.10 from

https://releases.ubuntu.com/23.10.1/ubuntu-23.10.1-desktop-amd64.iso

2. install far2l:

sudo apt install far2l

3. run GNOME Terminal
4. run far2l inside
5. press Arrow Up or Arrow Down keys several times being inside a non-empty folder
6. run far2l --nodetect=xi
7. try keys test once again

Still, ttyx module is helpful for clipboard access. So we should disable ttyx[i] input processing under Wayland automatically, but still use x11 clipboard API.
