Window.h is a rather heavy file, so let's try not to include it in header files when we can! Element.h now also includes LibWeb/Bindings/Intrinsics.h, but that's just out of my laziness. Most if not all objects call `Bindings::ensure_web_prototype<>()` anyway, so I don't think we would gain much by sticking the header to source files instead.
