move template from plone.app.workflow to plone.app.layout

news/3953.breaking

+Move the classic UI sharing page template and form handling to ``plone.app.layout``.
+The ``SharingView`` in ``plone.app.workflow`` now provides only the data/API methods;
+the base ``__call__`` raises a ``ValueError`` directing integrators to use the
+``SharingView`` override registered for ``plone.app.layout.interfaces.IPloneAppLayoutLayer``.
+Classic UI installations must depend on a ``plone.app.layout`` version that ships this override.
+The ``updateSharingInfo`` view and the ``Products.statusmessages`` dependency are removed.
