    ev-view-presentation: remove deprecated GdkScreen functions
    
    GdkScreen's monitor functions are deprecated since gdk 3.22.
    EvViewPresentation's gtk_window_set_transient_for() function uses
    gdk_screen_get_monitor_geometry() to get the monitor size. Replace this
    with gdk_monitor_get_geometry().
    
    Issue #1023
