David Zeuthen 472e6c8e18 Credstore changes for Android 12
- Add Credential.proveOwership()
- Add Credential.deleteWithChallenge()
- Add Credential.updateCredential()
- Add Credential.storeStaticAuthenticationDataWithExpirationDate()
  - Store this on disk. For entries stored without this parameter
    assume they never expire.
- Add allowUsingExpiredKeys to Credential.selectAuthKey() and
  Credential.getEntries()
  - Unless set to true, never select an expired key
- Introduce ERROR_NOT_SUPPORTED and return this if HAL does not
  support operation
