editeng: implement per-view LOK_CALLBACK_INVALIDATE_VISIBLE_CURSOR

Given that the per-view callback is in SfxViewShell, and editeng doesn't
depend on sfx2, add an interface class in editeng to invert the
dependency.

With this, gtktiledviewer no longer crashes when starting editeng text
edit with per-view callbacks.
