LibWeb: Make "top-level browsing context" concept more spec-compliant

Browse source 
Any browsing context that doesn't have a parent browsing context is now
considered a top-level browsing context. This matches the HTML spec.

This means we no longer keep a pointer to the top-level context, since
we can simply walk the parent chain until we find the topmost ancestor.
