[GTK] Implement resources API using injected bundle
https://bugs.webkit.org/show_bug.cgi?id=107457

Reviewed by Sam Weinig.

Source/WebKit2:

The ResourceLoaderClient was removed from the UI process in
r140285, and most of the GTK+ API depends on resources. This patch
implements the same API using the ResourceLoaderClient from
injected bundle. It fixes the resources unit tests, as well as
other 14 unit tests that are timing out because they depend on
resource API.

WebURLResponse and WebError objects in user messages.

WebURLResponse and WebError objects from user messages.
* UIProcess/API/gtk/WebKitInjectedBundleClient.cpp: Added.

to the WebView. For now it hanldes all the sresource loader client
messages.

webkitWebContextCreatePageForWebView() instead of
webkitWebViewBaseCreateWebPage() directly.
