fix patch-next by adding missing script (#81430)
The `patch-next.cjs` script is failing because two of its dependencies,
`pack-util` and `build-native`, are missing their CommonJS versions,
which are required for compatibility with the current Node.js
environment. To fix this, i added the transpiled `pack-util.js` and
`build-native.js` files.
