Andreas Kling 7bc9310170 LibHTML: Add a Frame class and use it for document layout width
Each HtmlView now has a main_frame(), which represents the main frame
of the web page. Frame inherits from TreeNode<Frame>, which will allow
us to someday implement a Frame tree (to support the <frame> element.)
