Summary: This PR aims to reduce code duplication by extracting `emitRootTag` logic from the flow and typescript folders into a shared parsers-primitives file. It is a task of https://github.com/facebook/react-native/issues/34872: > Extract the content of the case 'RootTag' (Flow TypeScript) into a single emitRootTag function in the parsers-primitives.js file. Use the new function in the parsers. ~~Note that https://github.com/facebook/react-native/issues/34898 should be merged first. I rebased on it's branch.~~ ## Changelog <!-- Help reviewers and the release process by writing your own changelog entry.
