IncognitoTabSnapshotController sets FLAG_SECURE when viewing incognito
tabs. The AssistStatusHandler is no longer needed. This CL deletes the
AssistStatusHandler and TabbedAssistStatusHandler.

In addition, this CL deletes the #addOverviewModeObserverPreNative in
ChromeTabbedActivity, and renames #addOverviewModeObserverPostNative()
to #initJourneyManager().
