[omnibox] Remove unused variation IDs from #omnibox-on-focus-suggestions

zero-prefix suggestions were enabled in the client option defaults in
cr/318496280 and the server-side zero-prefix configs were cleaned up in
cr/319310220. Thus, these forcing variation IDs are no longer needed to
trigger zero-prefix and can be removed from the client binary.
