Adam Colvin ef3991f1ed LibWeb: Implement Document.hasFocus() per specification ...

Previously, Document::has_focus() always returned true, which was
incorrect. This caused documents without a browsing context (such as
those created via document.implementation.createHTMLDocument()) to
incorrectly report that they had focus.

The implementation now follows the spec:
1. Return false if the document has no navigable
2. Return false if the top-level traversable doesn't have system focus
3. Walk the focus chain from the top-level document to verify this
   document is actually focused

This fixes a WPT test: "The hasFocus() method must return false if the
Document has no browsing context"
