Paul Gschwendtner 23118ef3d8 refactor(compiler-cli): fix ngcc cluster workers incorrectly being marked as busy with ESM (#43431) ...

Ngcc relies on cluster for distributing work. The master controller
sends messages to the workers as soon as the worker becomes `online`.
The online event is sent as part of the NodeJS cluster logic itself.

This does not work well because technically `online` could emit before the
worker started listening (this seems to be case now with ESM as the
imports are loaded in a way where `online` emits too early; before the
worker actually listens for messages).

We fix this by explicitly notifying the master when the worker
is ready for retrieving IPC messages/or tasks. This is more safe
anyway as it's not clearly specified when `online` emits.
