Fix booting performance issue

The efl_config is setting device scale information in booting time.
After EFL 1.20 migration, the booting time became longer than before.
It is because The Efl.Ui.Win uses a frame object which is NOT used on Tizen.
Please refer to following stack. The evas_font_load needs around 3 seconds.

  _evas_text_font_reload

  main ()

Setting device scale information does not need to use the frame object.
Moreover Tizen does not use the frame object. So we was about to use Efl.Ui.Win
without the frame object by checking _elm_config->win_no_border.

BUT, we might use Efl.Ui.Win frame object some day.
This patch set is making Efl.Ui.Win keep creating the frame object by checking
ecore_wl2 only (without Efl.Ui.Win).
