Support hasNavigationBar per display(1/2)

This change is to support Auto case.
Auto may need to support displays without navigation bar by default,
because the display may be far away from driver.
Note: currently, hasNavigationBar is global since it's from config.
  In future patches, it will also check hasSystemDecorations() on
  secondary display.
TODO: We may find a way to make OEMs set hasNavigationBar() for each
  display.
