REGRESSION (r140285): EFL uses WKPageResourceLoadClient which was removed
https://bugs.webkit.org/show_bug.cgi?id=107417

Reviewed by Gyuyoung Kim.

We had no choice but remove the ResourceLoadClientEfl after r140285
and thus our public API signals depending on it. The test_ewk2_auth_request
unit test was skipped because it depends these signals and will be fixed in a
different patch.
