ci: Split Docker builds into sequential release and max-perf stages

Separate fast release builds from slow max-perf builds to optimise runner utilisation and provide quicker feedback. Release builds complete first with standard optimisations, followed by Haswell-optimised dragrace builds once the safe builds pass successfully. Extract build logic into focused composite actions for better log visibility in Forgejo UI. Split monolithic build action into prepare-docker-build, inline docker build step, and upload-docker-artifacts to ensure each phase completes independently and shows logs immediately. Creates separate manifests at each stage to avoid waiting for all builds before publishing.
