[gtk/device-cleanup: 4/4] gdk: Drop axis labels

[Matthias Clasen <matthiasc src gnome org>]

commit 6292154aa182595d9f85d651abf3fa18c8df1692

    gdk: Drop axis labels
    
    This was only ever implemented on X11, and the labels
    here were atom names, so unlikely to be useful for
    anything interesting.
