Efl.Ui.Check: Fix unexpected activation

Efl.Ui.Check: Fix unexpected activation

This patch set has following upstream changes

(1) fd8e9f9 Efl.Ui.Nstate: do not call "changed" callback
    Before solving following problem in Efl.Ui.Check

    https://phab.enlightenment.org/T6673

    The changed callback is called with opposite value,
    if application is using Efl.Ui.Check with state pointer.

    The reason is that the changed callback is called in
    efl_ui_nstate_activate, and the value refered by state pointer
    is changed only after the efl_ui_nstate_activate is called.

    static void
    _activate(Evas_Object *obj)
    {
       EFL_UI_CHECK_DATA_GET(obj, sd);

       efl_ui_nstate_activate(obj);

(2) b1ee35e elm: do not call "changed" callback when setting style
