Current Status of use_frameworks!, versioned

[cipolleschi]

The goal of this thread is to provide a short documentation of the current status of the use_frameworks! settings for Cocoapods and iOS.

The following table represents how use_frameworks! support evolved with the various versions of React Native. As you can see, there have been regressions, but we now have tests in CircleCI that should prevents them from happening again.

We are committed to make sure that users can enjoy the New Architecture independently from their framework setup. This is also an important stepping stone to prepare React Native to support Swift and proper Clang modules.
