Added test for whether only fully active documents contribute to the joint session history
<!-- Please describe your changes on the following line: -->
The spec https://html.spec.whatwg.org/multipage/#joint-session-history says that only fully active documents contribute to the joint session history, but this appears not to be what's implemented.

Implement [Unforgeable]
This is mostly stolen from Gecko. As there, we define the unforgeable members
on an object stored in the slots of the prototype object. They are then copied
onto instance objects when they are instantiated. It should be noted that
proxy objects see their unforgeable memebers defined on their expando object.
Unforgeable attributes aren't properly inherited in codegen (in a similar
fashion as getters and setters as filed in #5875) and require to be redefined
in derived interfaces. Fortunately, there are currently no such interfaces.
No unforgeable members can be included into the TestBinding interfaces for good
measure because they are not compatible with setters.

Given the unforgeable holder object has the same prototype as actual instances
of the interface, the finalize hook needs to check its slot pointer for nullity
before dropping it.
The new failing test isn't related to Unforgeable attributes, but to the fact
that all Document instances currently have a Location, even if their window
isn't in a browsing context.
This is just the result of running --manifest-update on master; not sure
how it got out of sync.
These tests currently timeout, so also add the expected result.
