Add code to determine whether a Range in inside fixed position content
        https://bugs.webkit.org/show_bug.cgi?id=65720

        Reviewed by Dan Bernstein.

        Add an out param for various coordinate mapping functions
        that tells us whether the point or rectangle being
        mapped is inside fixed-position content.

        This brings back some of the changes from r89754.

        No behavior changes, so no tests.
