        [Freetype] Apply basic font properties as font variation settings
        https://bugs.webkit.org/show_bug.cgi?id=177039

        Reviewed by Carlos Garcia Campos.

        This patch makes sure that the basic font properties,
        such as `font-weight`, `font-width`, and `font-style`,
        are applied in the same way as `font-variation-settings`.
