Original change's description:
> Chrome OS Oobe: Show Ash dialog only if required
> 
> When starting a managed guest session (with no Terms of Service), a
> blank Ash dialog is shown for a brief moment before the session starts.
> This is caused by the Ash dialog for Oobe being shown even when all the
> Oobe screens are skipped.
> 
> This CL changes the behavior of the Ash dialog to only show when
> required by using a OobeUI::Observer. The dialog is not shown by
> default, and will be shown when a Oobe screen is shown.
> 
> OobeScreenWaiter now checks that the native window is visible by
> default. A small number of tests had to be changed to either show the
> native window or ignore the visibility check. The reasoning for the
> changes are in the comments for their respective tests.
> 
> The WebUI behavior is unchanged.
