Allow support for annotations with the same name / custom annotations

[ljacqu]

The injector only supports injection for @Inject -- however there are some other "flavors" with the same name but different packages. Maybe there could be an option to support any annotation type with the same name, or custom provided annotations.

This is probably even cooler to have now given that some annotations like @PostConstruct can be included from different kind of modules (e.g. Jakarta common annotations, whose package name has changed)
