Revert of Turn GoogleURLTrackerNavigationHelper(Impl) into a per-tab object. (https://codereview.chromium.org/283413002/)

Reason for revert:
Introduced flake on Mac: crbug.com/376550

Original issue's description:
> Turn GoogleURLTrackerNavigationHelper(Impl) into a per-tab object.
> 
> The goal of this CL is to eliminate the dependence of
> GoogleURLTracker(MapEntry) on NavigationController. To accomplish this goal,
> GoogleURLTrackerNavigationHelper is turned into a conceptually per-tab
> interface. GoogleURLTracker::OnNavigationPending() now takes in the
> GoogleURLTrackerNavigationHelper with which the navigation is associated rather
> than the associated NavigationController; GoogleURLTracker performs per-tab
> actions by calling the navigation helper associated with the tab.
> 
> A followup CL will turn GoogleURLTrackerNavigationHelper(Impl) into the
> GoogleURLTrackerDriver interface and ContentURLTrackerDriver implementation.
