a11y] Let links discovered by dataDetectorType be accessible (facebook#50914)

Summary:

The URL spans generated by Linkify are not actually accessible because we do not update the delegate's virtual views. 

I also had to change how AccessibilityLinks get generated, since it does not work well if it includes spans that are not `ReactClickableSpans`
