Ramanpreet Nara a997c0ac16 Implement 'onShouldStartLoadWithRequest' prop
Summary:
@public

This diff introduces the native backend for a new WKWebView prop: `onShouldStartLoadWithRequest`.

In the final component, the behaviour will be as follows: Whenever the user navigates around in the web view, we call `onShouldStartLoadWithRequest` with the navigation event. If `onShouldStartLoadWithRequest` returns `true`, we continue the navigation. Otherwise, we abort it.
