Root export PublicRootInstance and PublicTextInstance for ReactNativeTypes to use (#51018)

Summary:
Pull Request resolved: #51018

`ReactNativeTypes` deep imports  `MeasureOnSuccessCallback`, `PublicInstance`, `PublicRootInstance` and `PublicTextInstance`. The `MeasureOnSuccessCallback` type  is already root exported, `PublicInstance` is exported as `HostInstance` and there are two types left to export to root import all of them from react-native. This is needed for `simpleResolve` to properly resolve and build types located in `ReactNativePrivateInterface`.

This cannot be fixed on the resolver level because that would also involve change in the `exports` field in `package.json` to enable types resolution for deep paths which should be strict by design.
