Rewrite built-in modules to use CommonJS over ESM (#3814)
* stfdsafsd sadffdsa stuff finish commonjs stuff asdf not done but work not done but work not done yet but this is how far i am remove files lol update built files uncomment everything in events lol export default stuff * afdsafsd * its not perfect but almost done * okay * cool * remove temp file * finish rebase * revert settings.json * a * ch-ch-ch-ch-changes * okay * remove this check in release for now * sxdcfghnjm, * lkjhgf * fmt * filename can be null * Update NodeModuleModule.h * weee * fmt --------- Co-authored-by: Jarred Sumner <709451+Jarred-Sumner@users.noreply.github.com>
