tests: Add "accept_take_focus" command
When used it setups an X11 event monitor that replies to WM_TAKE_FOCUS ClientMessage's with a XSetInputFocus request. It can only be used by x11 clients on windows that have WM_TAKE_FOCUS atom set and that does not accept input. https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
