fix(@angular/build): Address build issue in Node.js LTS versions with prerendering or SSR

In Node.js 20, changes to ESM loader hooks result in the `--import` execArgv being passed from the parent to child workers.

This commit resolves the issue by setting an empty `execArgv` in the JavaScript transformer, preventing unintended propagation.

Closes #28683
