identity: Add VTS test to check that Identity Credential is implemented.

Android 14 VSR requires Identity Credential at feature version 202301
or later. This adds a test which verifies this.

Also bump the feature version of the default implementation to 202301.

Bug: 249767070
Test: atest IdentityCredentialImplementedTest
