Create menu windows in the correct seat

Add a mechanism to set the seat of a new display window, UI window,
UI popup - input device ID. This is set to the ID of the device which
activated the menu (mouse, keyboard). The display server determines
the correct seat from there.

This makes sure clicking outside closes the correct pop-up window.
