Send UpdateState when detaching a RenderFrame in FNE-enabled modes.

Send UpdateState when detaching a RenderFrame in FNE-enabled modes.

This ensures we do not lose PageState when navigating the main
frame, at least in the same-process navigation case.

Nasko, can you take a look?  This resolves one of the navigation layout tests,
where we were losing subframe form state after a same-origin main frame
navigation.  (It doesn't resolve the cross-process navigation case.)

LGTM
