Trigger wallpaper and zoom out even when blur is not supported.

This mimics what NotificationShadeDepthController was doing previously, when blur gets disabled it sets blurRadius to 0 and still schedules a frame callback for applying the zoom out.
New blur implementation does not invoke onBlurApplied when blur is not supported due to battery saver.
