API for individual attestation
Introduce a new API to request use of individual attestation
certificate for attesting keys generated by the
DevicePolicyManager.generateKeyPair method.
It builds on existing device ID attestation capabilities in two ways:
(1) Eligibility check: Assuming similar privacy requirements for the use
of individual attestation certificates, enforce the same conditions
for using them as the conditions for requesting device identifiers
in the attestation record.
(2) Keymaster interaction: Passing the right Keymaster tag to the
attestKey call, which is easily done in AttestationUtils.
Bug: 136494773
Test: CTS test to be added.
