Check all relevant fields of attestation report, not only the digest

[its-luca]

• exact difference between, CURRENT_TCB, COMMITTED_TCB and LAUNCH_TCB in Table 22. in https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/specifications/56860.pdf ? A bit more explanation is in https://www.amd.com/content/dam/amd/en/documents/developer/lss-snp-attestation.pdf Current vs launch kind of makes sense when you think about migration but comitted does not make sense to me
• digest of id key and auth key, if we used the id-block at launch
• information from the id block (family id etc), if we used it at launch

other relevant fields?
