This PR adds an optional step in sycl-linux-build to sign a build using the sigstore/cosign action. We should sign our release binaries. Currently we're performing it manually outside CI due to security reasons. But in future we'd like to switch to cosign instead. Therefore we're introducing this as part of nightly for now to test it in advance. Cosign insures that a blob was signed exactly by the specific workflow. Test run: https://github.com/intel/llvm/actions/runs/17404358377 To verify: cosign-windows-amd64.exe verify-blob \ --bundle /path_to/sycl_linux.tar.gz.sigstore.json /path_to/sycl_linux.tar.gz \ --certificate-identity https://github.com/intel/llvm/.github/workflows/sycl-linux-build.yml@refs/heads/BRANCH_NAME

Oops, now all workflows using sycl-linux-build need to grant additional permissions. Complicated + I don't think I really want to change the required permissions in sycl-linux-build. Probably I'll proceed with a dedicated workflow&job in nightly. |

Cosign ensures that a blob was signed exactly by the specific workflow.
