    workspace: Add meta_workspace_get_default_focus_window()
    
    Each workspace has a window that will be focused when switching to that
    workspace. Add a function to retrieve that window.
    
    This is only relevant for click-to-focus focus mode, since with the two
    other modes no window will be focused upon switching, and will only gain
    focus when hovered.
    
    This will be used in the next commit to make this window appear focused.
