API for verifying GPU integrity and authenticity through Attestation V4

Attest GPU V4 API Details:

Returns a detached EAT
Claims version: 2.0, 3.0, 4.0
The claims version 3.0, returns all claims, even if attestation fails. Uncalculated claims (due to errors) are set to null.
The claims version 4.0 adds support for the new opaque data format, reported in x-nvidia-mismatch-opaque-data-records and x-nvidia-attester-claims. Evidence that carries this opaque data must use claims version 4.0. See https://docs.nvidia.com/attestation/specs/latest/opaque-data.html.
