Browser Plugin: WebContnets should notify when it's restored

Renamed NOTIFICATION_WEB_CONTENTS_HIDDEN to NOTIFICATION_WEB_CONTENTS_VISIBILITY_CHANGED and
updated all appropriate places. We check for the detail false if we meant to check if the
WebContents is hidden. This matches the behavior of RenderWidget's
NOTIFICATION_RENDER_WIDGET_VISIBILITY_CHANGED.

Added a WasRestored method to WebContents public interface.
Call WasRestored from WebContents::ShowContents

BUG=128814
TEST=did not break existing autofill popup browser test
