Eliminate GoogleURLTracker having a Profile ivar

This CL eliminates GoogleURLTracker needing to have a Profile ivar by adding
APIs to GoogleURLTrackerClient to get the PrefService and
URLRequestContextGetter to use.

This CL additionally eliminates GoogleURLTracker's dependence on //chrome-level
prefs by moving the kLastKnownGoogleURL and kLastPromptedGoogleURL prefs into
the google component.
