Add support for @Nonbinding in @jakarta.inject.Qualifier annotations

[ghillert]

Affects: 5.3.2

In our project we reuse Java annotations across Framework boundaries (Spring/CDI/Micronaut). It turns our that Spring does not fully support the semantics of javax.inject.Qualifier annotations. Specifically, Spring Framework should support the marking of annotation fields with the @Nonbinding annotation. This would be especially useful when using @Bean methods together with org.springframework.beans.factory.InjectionPoint.

I have created a demo application to show the current behavior and desired behavior:

Please see especially:

It looks like @jhoeller aknowledged the issue in 2016:
