[gtk+/gtk-style-context: 384/490] GtkStyleProvider: Pass a GParamSpec in get_style_property().

[Carlos Garnacho <carlosg src gnome org>]

commit 59f0ce5e6a0dd005a7ed2caddef54c91984890c2

    GtkStyleProvider: Pass a GParamSpec in get_style_property().
    
    This is so we can know the owner type of the property, and matching
    with the stored strings in GtkCssProvider is direct.
