Use unified Gitlab pipeline for APM libraries

[randomanderson]

What does this PR do?

1. Converts the Gitlab workflow to use the unified pipeline.
2. Changes kubernetes library injection to work similar to how host injection works. Previously for k8s injection, dependencies were downloaded at runtime.

Motivation:

1. By using the unified pipeline across all APM libraries, there is less maintenance hassle, fewer mistakes, and a more uniform creation of artifacts.
2. Downloading dependencies at runtime is slow. Additionally some network policies do not allow pods to connect to the open internet which would prevent injection from succeeding.

How to test the change?
The changes were tested manually. CI/CD workflows are notoriously hard to test. Final products (OCI image and lib-init image) were run through automated onboarding tests.
