<pre>REGRESSION(<a href="http://trac.webkit.org/projects/webkit/changeset/185251">r185251</a>): [GTK] webkit_web_context_set_disk_cache_directory() doesn't work when using shared secondary process model after <a href="http://trac.webkit.org/projects/webkit/changeset/185251">r185251</a>
https://bugs.webkit.org/show_bug.cgi?id=145751

Reviewed by Darin Adler.

In <a href="http://trac.webkit.org/projects/webkit/changeset/185251">r185251</a> the CFNetwork cache was disabled in the web process,
but it also removed the disk cache directory web process
initialization parameter. While we support networking in the web
process when shared secondary process model is used, the network
cache should still work. We can remove this if we eventually
switch to use the network process unconditionally.

* Shared/WebProcessCreationParameters.cpp:
(WebKit::WebProcessCreationParameters::encode): Encode disk cache directory.
(WebKit::WebProcessCreationParameters::decode): Decode disk cache directory.
* Shared/WebProcessCreationParameters.h: Bring back disk cache directory only for soup.
* UIProcess/gtk/WebProcessPoolGtk.cpp:
(WebKit::WebProcessPool::platformInitializeWebProcess): Initialize disk cache directory parameter.
* WebProcess/soup/WebProcessSoup.cpp:
(WebKit::WebProcess::platformInitializeWebProcess): Use the disck cache directory parameter again.</pre>
