Summary Warn apps that use KVC on WKWebViewConfiguration about future breakage

We renamed some ivars in WKWebViewConfiguration in 276117@main. This broke some poorly behaved apps that were accessing ivars on WKWebViewConfiguration via KVC. We'll temporarily allow these apps to continue to function for backwards compat reasons when linking against an older SDK, but log a fault when it happens. When linking against newer SDKs, Foundation will raise an exception about trying to use KVC against a non-existent property for us.
