Hide navigation bar view immediately when folding to AOD

This CL addresses two problems with navbar visibility
when folding a foldable device to AOD:
* Hiding of navbar insets sometimes doesn't work when
  calling hide() immediately after creation of a window
  because of a race in insets controller.
  As a workaround added applying visibility to the
  view itself when doing the fold to AOD animation.
* Navigation bar creation happens in onConfigChange
  of SysUI and it is not synchronized with starting
  doze mode event from DozeService. So sometimes
  we skipped hiding the navbar because it hasn't been
  created yet at the moment when we started dozing.
  To avoid this issue added applying of the initial
  visibility to navigation bar when creating.
