x11: Mark XWayland as MODE_SWITCHING_EMULATED 

That way we don't do the awful minimise on focus loss logic by default on XWayland where mode switching is emulated (like on the Wayland backend).

This fixes CS2, Dota 2 minimising on alt-tab when playing in fullscreen (which is really annoying when managing eg. Discord on another screen)
