RFC: out-of-NPM package solution for React Native Artifacts

[cortinico]

Hey all, I'm sharing this RFC I wrote with the support of @renchap & @kelset to solve the problem of our NPM package size. We would love to hear the community's opinion on this change before we take any step in any direction.

We don't believe this change will affect users of React Native but will most likely affect advanced users such as library developers, SDK authors, developers of out-of-tree platforms that rely on our artifacts.
