[autotest] Add a test case for X11 fullscreen windows when an Wayland window is there

Browse source 
KWin cannot handle the layering correctly when a Wayland window is active
and there is a fullscreen X11 window. This test tries to simulate the
situation, but it does not show it.

Nevertheless it's a good test, so let's add it.
