Normally, assigning to e.g document.body.onload will forward to window.onload. However, in a detached DOM tree, there is no associated window, so we have nowhere to forward to, making this a no-op. The bulk of this change is making Document::window() return a nullable pointer, as documents created by DOMParser or DOMImplementation do not have an associated window object, and so must be able to return null from here.
