build: support linking of Angular libraries with rules_js

For linking of Angular packages we are using something more clever than
what we are doing with `rules_nodejs`. Instead of maintaing complexity
where we pre-link FESM bundles and somehow inject them into other Bazel
bundling steps (with complex linker mappings), we pre-link as part of
individual package postinstall steps, exposing the linked bundles via a
NodeJS exports condition.

This is possible vis this package/script:
https://github.com/devversion/angular-linking

Clearly this is not at a good location, but it's necessary right now to
ship this code via npm because `rules_js` struggles to use pnpm
extensions onto workspace 1st-party packages. Long-term we can either
decide to keep it that way, move it into e.g. dev-infra repository, or
we can explore shipping pre-linked bundles via APF. TBD.
