EachBean: Allow to inject the origin bean and the registration

[dstepanov]

For each bean functionality, we require a qualifier to properly identify the origin bean, but there are use cases where the bean cannot be modified.

Previously, we would allow each bean without a qualifier, but that will fail when you want to inject an origin; this PR is allowing to inject it.

Another solution for the qualifiers would be to add a qualifier that matches the bean type by the exact class, and maybe it can be reused elsewhere.

This should target 4.6 after it's created

[graemerocher]

don't think we should make this public API since it quite internal specific. Either way I would name it childOf or descendedFrom something.

Made private

what happens with a qualifier like this when I inject Map<String, Foo>? Please add tests for maps.

[dstepanov]

At this moment, it fails because there is no name. I think in this case we should throw an error saying that Map cannot be used on multiple beans that don't have the name defined.

[dstepanov]

I changed the message a bit reflecting that it doesn't need to be each bean + tests

[graemerocher]

I created the 4.6.x branch please target that. Also could you describe what issue this is trying to solve?

[dstepanov]

I want to add:

@EachBean(jakarta.ws.rs.ext.MessageBodyWriter.class)
public final class JaxRsMessageBodyWriter<T> implements MessageBodyWriter<T> {

    private final jakarta.ws.rs.ext.MessageBodyWriter<T> messageBodyWriter;

    JaxRsMessageBodyWriter(jakarta.ws.rs.ext.MessageBodyWriter<T> messageBodyWriter) {
        this.messageBodyWriter = messageBodyWriter;
    }

But Jax-Rs "beans" don't have any qualifier that fails when the origin bean is injected into the constructor.
