[NFC][Github] Move Container Composite Workflows to .github/actions (#166864)

This allows for their reuse inside llvm-zorg. Otherwise we get an error
that we cannot use reusable workflows inside job steps because Github
thinks that they are reuseable workflows rather than composite actions.
This should be NFC inside the monorepo.
