Reviewed by Tim Horton.

Add logic to set network connection integrity policy flags when sending a network request triggered
by a link element with `rel=preconnect`. See below for more details.

* Source/WebKit/UIProcess/API/Cocoa/WKWebViewPrivateForTesting.h:
* Source/WebKit/UIProcess/API/Cocoa/WKWebViewTesting.mm:
(-[WKWebView _networkProcessIdentifier]):

Add a testing hook that returns the network process PID, for use in a new (internal) API test.

* Source/WebKit/WebProcess/Network/WebLoaderStrategy.cpp:
(WebKit::policySourceDocumentLoaderForFrame):

Pull existing logic for grabbing a suitable `DocumentLoader` for a given frame out of
`addParametersShared` and into a separate helper function, so that we can use it in multiple places.

(WebKit::addParametersShared):
(WebKit::WebLoaderStrategy::preconnectTo):

Use the new helper function above to populate network connection integrity flags on the outbound
resource load when handling preconnect.

* Tools/TestWebKitAPI/cocoa/HTTPServer.h:
* Tools/TestWebKitAPI/cocoa/HTTPServer.mm:
(TestWebKitAPI::HTTPServer::totalConnections const):

Add a helper method on the mock HTTP server to return the total connection count.
