changed_set method is already used in Evas.Object_Smart.
elm_glview_changed_set requests Elm_glview for drawing, so change the API to
elm_glview_draw_request_set.
During the migration of docs to the eo file the group name changed to have a
Elm_ prefix which resulted in our docs not including this group and not showing
any of the docs in there. Switching to the new name fixes this.
Having this prefix makes sense especially as we are now merging elm into efl.
