Summary:
elm_bg was supposed to be used only in legacy,
but since we need a common object to be used as a background of widgets,
it is now renamed as efl_ui_bg and supports EO APIs.

Differential Revision: https://phab.enlightenment.org/D5147
Wherever the EO API is used, i.e. efl_add() is used to create evas
objects, we can skip the calls to set fill/expand.
This new set of defaults indeed saves ~60 loc in the tests (out of 115
objects created). I found only 3 cases where the align had to be set
manually (to the old default of 0.5).

Ref T5301
All windows should be standard, really. Except when using legacy
elm_win_add() or if type_set() was called with a specific type.
I dislike type_set...
Ref T5322
Use Efl.Part for window to manipulate the background.
Two part names are used in EDC:
- elm.rect.background
- elm.swallow.background
For apps the part name is only "background".
To set a solid color background (alpha is ok):
efl_gfx_color_set(efl_part(win, "background"), r, g, b, a);
To set an image:
efl_file_set(efl_part(win, "background"), "image.jpg", NULL);
To set an object:
efl_content_set(efl_part(win, "background"), subobj);
The solid bg is invisible by default, will become visible and use
COPY render mode if a color is set. Standard window uses the
swallow part.
