Summary:
For now, how to check whether a widget is legacy or not
is to check flags in private data or static flag, which is set
during elm_legacy_add.
If Efl.Ui.Legacy interface is added, it can be easilly checked
by efl_isa(obj, EFL_UI_LEGACY_INTERFACE)

Revert "Separtor: use orientation APIs"
This reverts commit f043c3be61.
Separator is not part of EO API so no need to use Orientation or
Direction API here.
Ref T5870
Some names have not been changed, hopefully making a distinction
between legacy APIs and internal code (elm_layout_blah) and valid EO
usages.
This means many internal functions are still elm_layout_ as their
sole purpose is to support the legacy API.
Ref T5315
elm_layout_sizing_eval() marks an object as requiring recalc.
Unfortunately, it's been massively abused by various widgets into
actually doing the calc, or the min calc. So we end up with one API
that has 3 different definitions depending on the widget type:
1. Mark as requiring recalc (correct, respects doc, elm_layout)
2. Calculate min size and other size hints
3. Actually do some geometry modification
I believe we need to clarify these 3 requirements into 3 very clear
and specific APIs in elementary. Right now we have similar functions
in evas for 1 (evas_object_smart_changed) and 3 (smart_calculate).
But their exact definition also isn't necessarily what we want for
elementary.
Another clear problem is that layout_eval does not do any calculation
(in theory), so the "eval" word is a bit of a stretch here.
Once we're sure about the exact API we want, we can add this back to
EO and make it work across our EO widgets. For now let's just keep
the legacy API, and its EO overrides, as is.
Ref T5315
Now you can't use the same syntax as you would for a method to
implement a property as whole, instead you need to specify the
getter and/or setter explicitly. This is to allow parent classes
to expand their properties without altering behavior of the child
classes.
