Efl - efl_model_base changed to use eina_promise
Eio - eio_model use efl_model_base with promise
Eldbus - elddbus models use promise now
Elementary - elm_view_list and elm_view_form use new models with promise
updated all related examples and tests
I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
