Andreas Kling 8fabaaa2a8 LibWeb: Make "top-level browsing context" concept more spec-compliant ...

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.
