edje: support legacy Textblock calculation logic for 1.18 edje file

Summary:
From EFL 1.19, Edje Textblock calculation logic was fixed according to
Edje documents. But, it broke old edje files which ignored text.min
option for minimum width. Even if the old edje files were wrong,
we need to support them as discussed from T5548.

Also, this patch will change default efl_version to 1.18 from 1.19.
So, without efl_version property, edje file will run on the legacy logic.

Fixes T5548

Test Plan: Turn on/off presentation mode in Enlightenment.
