feat: migrate google-devtools-containeranalysis to librarian (#8534)

* chore: migrate google-devtools-containeranalysis to librarian

* chore: generate Grafeas v1beta1 client in containeranalysis for backward compatibility

* chore: restore Grafeas v1 path helpers in ContainerAnalysisClient

* chore: remove GrafeasClient from top-level exports to match main

* chore: use regex in librarian.js to clean up system-test samples
