 * Build the `zone.js` npm package into `dist/bin/packages/zone.js/npm_package/` and copy it to
 * `destDir` for other scripts/tests to use.
 *
 * NOTE: The `zone.js` package is not built as part of `package-builder`'s `buildTargetPackages()`
 *       nor is it copied into the same directory as the Angular packages (e.g.
 *       `dist/packages-dist/`) despite its source's being inside `packages/`, because it is not
 *       published to npm under the `@angular` scope (as happens for the rest of the packages).
 *
 * @param {string} destDir Path to the output directory into which we copy the npm package.
 *     This path should either be absolute or relative to the project root.
