LibWeb: Remove unecessary dependence on Window from DOM and WebIDL

Browse source 
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.
