[Codegen] Extracts modules/utils.js files from the flow and typescript folders in parsers-commons

[AntoineDoubovetzky]

Summary

This PR is a task from #34872
Extract the modules/utils.js from the flow and typescript folders in a shared parsers-commons.js file. Then, have the two parsers use the same wrapModuleSchema function for modules.
(wrapModuleSchema is a copy-paste mistake, in this case it is wrapNullable and unwrapNullable)

Changelog

[Internal] [Changed] - Extracts Codegen's modules/utils.js files from the flow and typescript folders in parsers-commons

Test Plan

I ran yarn jest react-native-codegen:
