add privacy manifest to React-cxxreact

Summary:
Changelog: [Internal]

add this to the framework's resource bundle

reasons:
  - C617.1 (JSBigString)

current problem with this method is that the required reasons are not currently be aggregated during app store review, so those need to live in the app's. but go ahead and add it here for now, i think apple will try to fix it.
