Reviewed by Brady Eidson.

Currently we unconditionally handle all WKApplicationUtilities links in WebKit without notifying the
embedder via the navigation delegate.

To be more consistent with other types of link handling, we should instead notify the navigation
delegate about such links, and only handle them in WebKit if the embedder responds to the delegate
callback telling us to process that link (e.g. via WKNavigationActionPolicyAllow).
