Subject: [PATCH] Move flow definitions to react-native

Summary:
These definitions make these libraries act as flow strict. We have them internally but need them in react native to be able to make files in react native flow strict.

Internally our flowconfig includes all the configs in react-native-github.

Changelog:
[Internal]: Add flow strict type definitions for modules
