        Create SVG and WML elements with create functions instead of direct invocations of new
        https://bugs.webkit.org/show_bug.cgi?id=44851

        Added the create functions, made some existing constructors protected and private,
        made some other member functions protected and and private, added some missing virtual
        keywords for clarity to functions that already were overriding virtual functions,
        fixed some inconsistent indentation, and removed some unneeded empty destructors.

        In the future, it will be good to have the constructors all be private so we don't
        use them by accident. Then we'll change the reference count rule globally and add
        all the necessary calls to adoptRef.

        The SVG changes are compiled and tested. The WML changes are speculative and untested.

        * dom/make_names.pl: Removed supportfor the createWithNew keyword.
        * svg/svgtags.in: Removed all the createWithNew keywords.
        * wml/WMLTagNames.in: Ditto.
