Paul Gschwendtner 9cd89569f5 build: create NodeJS ESM loader for supporting Bazel setup (#48521)
Replaces the existing ESM loader for dealing with external module
imports. This loader was introduced by Aspect for AIO `.mjs` scripts.

The loader will be used as foundation for a more extensive loader
that also properly handles first-party packages.

Additionally another loader is added, all packed as a single
loader because our current NodeJS version only supports a single
loader per node invocation. So we implement chaining ourselves.

The new loader will attempt rewriting `.js` extensions to `.mjs`,
also it will add `.mjs` if not already done. This is necessary
in the transition phase because we don't/cannot use explicit `.mts`
extensions and also we don't specify extensions in imports yet.

Long-term we would likely use `.mts` and explicit import extensions,
but it's not yet clear how we would sync this into g3 too.

third_party vendored sources in Angular

TL;DR: don't copy sources into this repo

All sources in this repo should be authored from scratch by the committer. Don't copy sources you've found in any other location.

What if I have a good reason?

We do "vendor in" some sources, in cases where we do not want our users to have a transitive dependency. For example, to make testing more reliable, we copy a font into our repo. That allows our integration tests to run without dynamically requesting that font.

Follow these guidelines for adding sources under third_party:

  1. Only vendor sources with compatible licenses. Apache 2.0 and MIT are good. Any other licenses, check with your team lead so we can verify our ability to comply with the license.
  2. Preserve the license for code. The best thing to do is copy the entire LICENSE file along with the sources.
  3. Indicate where the sources came from. Our convention is to create a directory based on the URL where the sources were fetched. Add version number or if missing, the retrieval date, as a comment in the build file just above the license() call. Example: https://github.com/angular/angular/blob/master/third_party/fonts.google.com/open-sans/BUILD.bazel
  4. Avoid changing the files you fetched. If you make any changes to the sources, first commit the original, then in a separate commit, make your edits. include another metadata file listing your changes, like https://github.com/bazelbuild/rules_nodejs/blob/master/third_party/github.com/source-map-support/LOCAL_MODS.md
  5. Any bundle or distribution which includes this code needs to propagate the LICENSE file or content. Talk to your TL to make sure this is done correctly.

Under Bazel

This directory is treated specially by Bazel.

All BUILD.bazel files under third_party are required to have a licenses statement. See https://docs.bazel.build/versions/master/be/functions.html#licenses

Note that we don't yet have a way to enumerate the licenses and include them in our distribution. Follow https://github.com/bazelbuild/bazel/issues/188
