Add some network connection integrity testing support

https://bugs.webkit.org/show_bug.cgi?id=249651

Reviewed by Aditya Keerthi.

Add support for API tests for lookalike character sanitization.

* Source/WebKit/UIProcess/API/Cocoa/WKWebViewPrivateForTesting.h:
* Source/WebKit/UIProcess/API/Cocoa/WKWebViewTesting.mm:

Leave a FIXME here, explaining that this testing hook can be removed once the API calls into the
associated system framework can happen directly in the UI process, without having to go through the
network process.

(+[WKWebView _setLookalikeCharacterStringsForTesting:]):
* Source/WebKit/UIProcess/WebPageProxy.h:
* Tools/TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
* Tools/TestWebKitAPI/Tests/WebKit/NetworkConnectionIntegrityTests.mm: Added.

Add a WebKitAdditions extension point, which will contain the new API tests.
