Instead of creating a new global object and proxying everything through it, we now evaluate console inputs inside a `with` environment. This seems to match the behavior of WebKit and Gecko in my basic testing, and removes the ConsoleGlobalObject which has been a source of confusion and invalid downcasts. The globals now live in a class called ConsoleGlobalObjectExtensions (renamed from ConsoleGlobalObject since it's no longer a global object). To make this possible, I had to add a way to override the initial lexical environment when calling JS::Interpreter::run(). This is plumbed via Web::HTML::ClassicScript::run().
