Subject: [PATCH] fix: add isChildPublicInstance to ReactNativeTypes (#27788)
 (#41807)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/41807

Changelog: [Internal]

Follow-up on https://github.com/facebook/react/pull/27783.

React Native is actually using `ReactNativeTypes`, which are synced from
this repo. In order to make `isChildPublicInstance` visible for
renderers inside React Native repository, we need to list it in
`ReactNativeTypes`.

Because of current circular dependency between React Native and React,
it is impossible to actually type it properly:
- Can't import any types in `ReactNativeTypes` from local files, because
it will break React Native, once synced.
- Implementations can't use real types in their definitions, because it
will break these checks:
