Reviewed by Gyuyoung Kim.

Currently, size of the viewport is larger than size of webview.
Changed the size of viewport with size of webview, because viewport is translated by wrong calculation.

* UIProcess/API/efl/EwkView.cpp:
(EwkView::displayTimerFired): Changed to use the (0,0).
(EwkView::createGLSurface): Modified to use the viewSize instead of the boundsEnd.
(EwkView::handleEvasObjectCalculate): Removed the WKViewSetUserViewportTranslation.
