Updates the service-worker package to export the worker script and
schema, so that these files can be resolved and included by consumers.
Additionally, the CLI bundle is updated to be using ESM as it
transitively relies on the `core` entry-point of the package which
already uses ESM. Also this is required because the script is part
of the the service-worker package which has `type: module` applied.

This service worker is a conceptual derivative of the existing @angular/service-worker maintained at github.com/angular/mobile-toolkit, but has been rewritten to support use across a much wider variety of applications.
Entrypoints include:
@angular/service-worker: a library for use within Angular client apps to communicate with the service worker.
@angular/service-worker/gen: a library for generating ngsw.json files from glob-based SW config files.
@angular/service-worker/ngsw-worker.js: the bundled service worker script itself.
@angular/service-worker/ngsw-cli.js: a CLI tool for generating ngsw.json files from glob-based SW config files.
