        Make it possible to enable the new HTML5Tokenizer for testing
        https://bugs.webkit.org/show_bug.cgi?id=39275

        I added html5ParserEnabled to Settings so that we can enable/disable
        the HTML5 parser for testing.

        I also ripped out a bunch of dead code from HTML5Lexer.

        I had to add HTML5Lexer/HTML5Tokenizer to all build systems so that
        the build wouldn't fail now that we reference these classes from HTMLDocument.
