workflows/build-ci-container: Add an arm64 container (#120828)

This also changes the container version numbers in the tag from unix timestamps to the abbreviated commit hash for the workflow. This ensures that the amd64 and arm64 containers have the same tag. For amd64 we now generate 4 tags: * ghcr.io/llvm/ci-ubuntu-22.04:latest * ghcr.io/llvm/ci-ubuntu-22.04:$GITHUB_SHA * ghcr.io/llvm/amd64/ci-ubuntu-22.04:latest * ghcr.io/llvm/amd64/ci-ubuntu-22.04:$GITHUB_SHA For arm64 we generate 2 tags: * ghcr.io/tstellar/arm64v8/ci-ubuntu-22.04:latest * ghcr.io/tstellar/arm64v8/ci-ubuntu-22.04:$GITHUB_SHA
