Allow qualifiers to be specified for the build-in authentication mechanisms

[arjantijms]

Jakarta Security provides a number of build-in authentication mechanisms. These are enabled via a ...Definition annotation which adds a Bean<T> to CDI's beans with among its types HttpAuthenticationMechanism. We don't know the actual type of it, as that is implementation specific.

In the case that we enable multiple authentication mechanisms, we can't see which one was created via which ...Definition annotation. I.e. we don't know if it's a basic authentication mechanism or a form one, etc.

To solve that problem, we should introduce qualifiers for the ...Definition annotation. Via such qualifier we can inject and/or introspect beans.

I believe this, together with #309, would more or less resolve #188.
