This commit updates the implementation of the fake navigation to more
closely follow the spec. This includes links to spec parts as well as
some reorganization to have the flow of the code more exactly follow the
corresponding steps in the spec. This makes it easier to verify that th
behavior is correct.

The navigate event was only ever being cleared when a new navigation
happened. That new navigation would abort the previous one, even if it
had already finished successfully.

This moves the `FakeNavigation` implementation to the primitives folder
so its implementation can be shared with Wiz. This class was initially
copied directly from the Wiz implementation, with some small modifications.
There will still need to be some work done to align the implementations
and fix anything internally that needs adjusting.
