Revert 229285 "Gets hiding animations to work again"

> Gets hiding animations to work again
> 
> This broke when bounds changes was consolidated into
> DesktopNativeWidgetAura::OnRootWindowHostResized. We can't resize the
> child layers when this happens as otherwise we're going to force a
> paint of the layers and thus the views. But at this point nothing is
> valid and we don't want to paint anyway.
> 
> Also removing a call to Show() early on as it may trigger animations
> that we don't want. A Show() at this time is before the creator has
> had a chance to turn them off.

> BUG=none
> TEST=none
