Update Identity Credential VTS tests.
These updates are based on input/experiences implementing this
HAL. There are no API changes.
- Specify that the validity for credentialKey certificate shall be
from current time and expire at the same time as the attestation
batch certificate.
- Require challenge passed to getAttestationCertificate() is
non-empty.
- Fix bug in VTS tests where the startPersonlization() result was not
checked.
- Remove verifyStartPersonalizationZero test since it cannot be
completed.
- Ensure secureUserId is non-zero if user authentication is needed.
- Specify format for signingKeyBlob in generateSigningKeyPair() same
way we do for credentialData in finishAddingEntries().
- Modify EndToEndTest to decrypt/unpack credentialData to obtain
credentialPrivKey and storageKey and do cross-checks on these.
- Modify EndToEndTest to decrypt/unpack signingKeyBlob to obtain
signingKeyPriv and check it matches the public key in the returned
certificate.
- Add new VTS tests for user and reader authentication.
- Relax unnecessary requirements about SessionTranscript structure -
just require it has X and Y of the ephemeral key created earlier.
- Allow calls in VTS tests to v2 HAL to fail - this should allow
these VTS tests to pass on a compliant v1 HAL.
