[Sync] Propagate XMPP auth errors to SyncNotifierObservers
Detect XMPP auth errors and add new notifications to SingleLoginAttempt
and Login.
Replace PushClientObserver::OnNotificationStateChange with
OnNotifications{Enabled,Disabled} notifications.
Change SyncNotifierObserver similarly.
Handle InvalidationClient errors and propagate auth errors from that,
too.
Propagate XMPP auth errors all the way up to SyncManager. It will be
handled in a future CL.
