Python API: Tag for update on object.update_from_editmode()

This call modifies geometry but does not inform anyone about
changes.

After this change it's possible to load edit mesh, then request
evaluated dependency graph and do some interesting things with
the updated object.

This is part of T63244: object.to_mesh ignores object.update_from_editmode
