test: Add a test for "activate" hammering

Browse Source 
This is what "terminator" (the terminal emulator) does, it basically
calls gdk_window_focus() in a loop thousands of times at startup.

This in turn fills up the Wayland connection between Xwayland and
mutter, and eventually the session dies.
