[gtk+] switch: Deprecate style properties

[Matthias Clasen <matthiasc src gnome org>]

commit abbd6b11f6c01810a2bf3a9fa5a32b2d4224228c

    switch: Deprecate style properties
    
    CSS min-width and min-height on the slider node fit this
    perfectly. We still fall back to the slider-width and
    slider-height style properties if the CSS properties are
    not set.
