Add WPTs for Window object reuse when navigating from the initial empty document

No browser appears to implement the behavior defined in the HTML spec.
The test expectations are currently baselined to Firefox, which appears
to be the closest match.

Firefox appears to reuse the Window object iff the \<iframe> load
event has never fired and the a same-origin navigation commits. In
particular, this means that an \<iframe> with no src attribute set can be
inserted into the DOM and synchronously navigated, yet still reuse the
Window object if the asynchronous navigation commit is same-origin.

In contrast, Chrome only reuses the Window object iff the \<iframe>
element has a src attribute set when inserted into the document;
otherwise, the Window object will never be reused. IE also appears to
implement similar behavior.
