fonts: GetRasterizerCaps hinter enabled flag

[Huw D M Davies]

        Huw Davies <huw at codeweavers.com>
        Add a Wine specific flag to GetRasterizeCaps that reports
        whether freetype's patented hinter is enabled.  This will
        be used by winex11 to check whether it should honour the
        gasp table settings.
