@ArgumentSource annotations cannot be used as a repeatable annotation on composed annotations

[marcphilipp]

All @ArgumentSource annotations are lacking the ElementType.ANNOTATION_TYPE value from their @Target annotation. Thus, it's currently impossible to use them as repeated annotations when declaring a composed annotation; i.e., the following currently does not compile:

@ValueSource(ints = 1)
@ValueSource(ints = 2)
@interface Example {}

Deliverables

• Ensure all @ArgumentSource annotations can be used as a repeatable annotation on composed annotations
• Remove exclusion in ArchUnitTests
• Backport to 5.11.x branch
