sd lok: implement SfxViewShell::NotifyCursor() API

The same API is already implemented in sw and sc already, the sd
implementation allows selecting a shape in one view, then creating a
second view, and seeing the selection of the first view in the second
view, without de-selecting and re-selecting the shape in question in the
first view.
