ecore_evas_activate API .
like _ecore_evas_x_activate API, we need to _ecore_evas_wl_common_activate work well in wayland 2.
in tizen, ECORE_WL_WINDOW_ACTIVATE/DEACTIVATE event exist, but I think we don't need this event anymore (but I'm not sure).
would you discuss this event can be removed with philippe.coval?
Usecase: backward compatability.
If the task was alredy implemented, we will close this task.(To check that the task is alredy implement can be task)
