Deployment should fail if annotations contain invalid attributes

As confirmed by Will (https://javaee.groups.io/g/javaee-security-spec/message/341), identity stores with invalid values should fail the deployment. The same applies for authentication mechanisms.

I'll start to work on this later today.

Start by tracing deployment validation for identity-store and authentication-mechanism annotations, then review the discussion linked in the issue for the expected failure behavior. Check existing deployment tests if available; done means deployment rejects invalid annotation attribute values for both kinds of security configuration.
