Adam Comella cfe003238a iOS: Introduce API for making screen reader announcements
Summary:
This change introduces some APIs that are useful for making announcements through the screen reader on iOS:
  - `announceForAccessibility`: The screen reader announces the string that is passed in.
  - `announcementFinished`: An event that fires when the screen reader has finished making an announcement.

You can already solve similar problems with RN Android using the `accessibilityLiveRegion` prop. Live regions are a different feature but they can be used to solve the same problem. This commit does not attempt to add live region support in RN iOS because Apple did not build live region support into iOS.

Verified that `announceForAccessibility` causes VoiceOver to announce the string when VoiceOver is enabled. Verified that `announcementFinished` fires with the appropriate data in the event object. Additionally, my team has been using this change in our app.
