Implement 'dataDetectorTypes' prop

Summary:
When text is rendered in `WKWebView` WebKit component, the component itself can detect things like phone numbers, flight numbers, links, etc. and render them with additional functionality.

For example, when the text `apple.com` is detected, if the `link` data detector type is enabled, the web view will actually render a link that takes the user to the Apple home page.

In this diff, I implement the `dataDetectorTypes` prop. The data detector types supported are:
1. phoneNumber
1. link
1. address
1. calendarEvent
1. trackingNumber
1. flightNumber
1. lookupSuggestion

These enums are documented in the [[ https://developer.apple.com/documentation/webkit/wkdatadetectortypes | WKDataDetectorTypes docs ]].
