    x11: Do not try to access private structures
    
    ClutterInputDeviceX11 has been made private, so we cannot access it from
    outside of clutter-input-device-core-x11.c. We should have simple
    accessors for the min/max keycode, which is the only detail that we use.
    (cherry picked from commit 1dc7c4543896bfc2f2cd460cdea9c417aefd7952)
