Replace dependencies with needs in CI/CD pipeline

Overview

This is part of the pipeline speed improvements described in #6213 (closed)

This MR changes the review and deploy_* jobs in the deploy stage to use the needs keyword instead of the dependencies keyword, and use the Directed Acyclic Graph support.

It should make the merge request branches faster, because the deploy stage jobs will no longer wait on the unnecessary build stage jobs, for example code_quality, dependency_scanning and the spec jobs. Plus, these jobs are either allowed to fail anyway, or not run on master.

Important Note

In merge requests, this could result in broken or invalid code getting deployed if the build stage jobs end up failing, but the MR should not be able to be approved or merged until the failing build is fixed.
