LibWeb: Remove unecessary dependence on Window from DOM and WebIDL
These classes only needed Window to get at its realm. Pass a realm directly to construct DOM and WebIDL classes. This change importantly removes the guarantee that a Document will always have a non-null Window object. Only Documents created by a BrowsingContext will have a non-null Window object. Documents created by for example, DocumentFragment, will not have a Window (soon). This incremental commit leaves some workarounds in place to keep other parts of the code building.
