Identity Credential: Pass additional information to HAL. 

Without this extra information passed upfront it's not practical to
implement a HAL which incrementally builds up cryptographically
authenticated data.

Two new methods are added to facilitate this and the HAL version
number is bumped to 2.

Bug: 154631410
Test: atest VtsHalIdentityTargetTest
Test: atest android.security.identity.cts
