[EFL][WK2] Add tests of the set process model API
https://bugs.webkit.org/show_bug.cgi?id=130830

Patch by Maciej Florek <m.florek@samsung.com> on 2014-03-27
Reviewed by Gyuyoung Kim.

Implement unit tests to check, if process model API works
properly. When process model is set to EWK_PROCESS_MODEL_SHARED_SECONDARY,
there should be only one WebProcess. In case of EWK_PROCESS_MODEL_MULTIPLE_SECONDARY
setting, each WebView should have own process, as well as the network process
should exist.
