[EFL][WK2] Fix test_ewk2_view unit test timed out issue
https://bugs.webkit.org/show_bug.cgi?id=117251

Reviewed by Christophe Dumez.

'ewk_view_contents_size_changed' unit test case has been timed out since r150802 because
same size is filtered by WebView class. So create one different test html string that has
different size to continue unit tests.

* UIProcess/API/efl/tests/test_ewk2_view.cpp:
(onContentsSizeChangedPortrait):
(onContentsSizeChangedLandscape):
(TEST_F):
