Artifact attestation

[praveen5959]

Description

• Updated permissions for build jobs to include id-token: write, contents: read, and attestations: write to enable artifact attestation.
• Added a step in each build job (Linux, Windows, Mac) to generate artifact attestation using actions/attest-build-provenance@v1 after the binary is built and renamed.
• Ensures build provenance for binaries is included in releases for enhanced security and traceability.
