indicator_format_set/get & indicator_format_function_set are
now legacy APIs.
indicator format can be set by using generic Ui.Format function
e.g.
efl_ui_format_string_set(efl_part(sliderObj, "indicator"), "1.0%f");
This generic format_string would be used in slider,progressbar
and other widgets.This default function handles INT
and DOUBLE eina value types for now.

Reasons:
- This API has been confused with the min size of the widget, resulting
in badly laid out applications.
- The EO API was not very nice (Range is about numbers, the Gfx size
hint in a part is really ugly).
While I understand the value of this API and how it can be used in
scalable applications, it is in fact not absolutely necessary.
Alternatively to that span size, the widget min size can already be
defined from the application side, or the widget can simply be expanded
to fill in its parent.
This can obviously be reinstated later if the need arises for EO. For
now, keep this feature as legacy-only.
