Navigating back to page with previously active web env leaves UI stuck
showing active state

Reviewed by Etienne Segonzac.
Trigger the state exit of the old immersive element and queue the
immersivechange notification when the document is about to
enter the back/forward cache, mirroring how pointer lock is torn down at the
same call site.
Since the Immersive environment cannot survive navigation, it is safe to clear
the immersive document state at this point,
to get back from a clean slate if the user navigates back to this page.
Sending the event to the page ensures that it updates its UI and doesn't stay
in a stale state thinking that the
immersive environment is still up.
