    window: Check window responsiveness on every window focus
    
    Increase the number of checks whether a window is still responsive and
    ping windows on every call to `meta_window_focus()` instead of
    `meta_window_activate_full()`. This ensures the window is also pinged in
    case normal interaction like clicks on the window happen and a close
    dialog will eventually get shown.
