Summary:
See https://github.com/facebook/react/pull/18366
This contains a fork of the upstream Flow types. We shouldn't be syncing this since these leads to conflicting types.
As a result, these uses have already been codemodded away. Only the imports remained.
Changelog:
[React Core] - Remove ReactTypes from sync.
