Revert 191376 "Propegate setting autohide behaviour to prefs"

> Propegate setting autohide behaviour to prefs
> 
> When the ShelfLayoutManager changes the autohide behaviour this needs to be
> propegated to the ChromeLauncherController otherwise when other parts of the
> system query the autohide status they can end up with an incorrect value. This
> resolves most of the outstanding issues with the "Autohide Launcher" checkbox in
> the context menu.

> These is still one issue, specifically if you set autohide off, swipe the
> launcher off the screen and then make it reappear, via either swiping or mouse
> over. The checkbox will not be checked in this case, but the moment you touch or
> click off of the launcher it will hide. After hiding the checkbox will be set as
> expected, thus partially resolving that fact that you had to turn on autohide
> before you could turn it off. This issue due to the fact that the
> ShelfLayoutManager is actually turning off autohide, but setting a handler to
> watch for future events and when you interact outside of the launcher setting
> autohide on again. Resolving this is outside the scope of this CL/bug since it
> either requires changing our UI behjaviour or plumbing information about being
> in this state to the LaunchContextMenu, both of which would be unlikely to be
> backported to 27.
