Resize WebPage's viewport size ealier

[Title] Resize WebPage's viewport size ealier
[Issue#] DCM-1848
[Problem] Sometimes JS window.innerWidth returns 0 on launching time
[Cause] WebPage's viewport size is fixed too late. It was resized on
        _ewk_view_smart_calculate() not on _ewk_view_smart_resize(). There's
        time delay between _ewk_view_smart_resize() and _ewk_view_smart_calculate().
[Solution] Resize viewport size right after _ewk_view_smart_resize() is called
