[gtk+/win32-theme2: 3/18] Remove _gtk_style_properties_peek_property

[Alexander Larsson <alexl src gnome org>]

commit 7104b4b575d85795186582251216eb23c4b6e5c8

    Remove _gtk_style_properties_peek_property
    
    We want to move to a world where getting style properties can
    allocate a new value, depending on the style property context.
    In this world we can't expose "peeking" a property, as we neet
    to return a ref to the property that is newly created.
    
    So, we move the peek code into get_property and use get_property
    from get_valist.
