efl_ui_image: update orientation immediately

efl_ui_image: update orientation immediately

Summary:
It is able to get orientation information of inlined image object.
This information should be same during its life time.

The inlined image object got correct information only after size
calculation, so there is a kind of timing issue.

An example will be attached for more details.

I am not sure what the regression bug mentioned on D6855, but
this will keep compatibility of behavior.

Actually it seems that the compatibility was broken by D9686
which does not call _efl_ui_image_sizing_eval immediately.
