Prepare ReactNativePrivateInterface for new React renderer calls to h…

…andle root/document nodes (facebook#49010)

Summary:

Changelog: [internal]

This adds a stub method for `ReactNativePrivateInterface.createPublicRootInstance`, which just returns `null` for now, so we can synchronize the React renderer that will try to use it to create root instances.

Initially, this will not do anything and React will just pass the `null` value around. When we implement the document API, we will return a proper instance and React will pass it to `createPublicInstance` so we can link things at runtime.
