Remove dependency on quarkus-test-common in independent-projects/arc/tests

[gastaldi]

This removes the dependency on quarkus-test-common as discussed in https://quarkusio.zulipchat.com/#narrow/stream/187038-dev/topic/arc.2Ftests.20is.20not.20so.20independent/near/226379353

@gastaldi I think there is little point in re-declaring the mock annotation in Arc tests - the purpose of the test was to cover the @io.quarkus.test.Mock feature.
Therefore, to be free of the dependency and keep the tests sensible, we'd need to take these tests and move them into another module.

Are you sure? The tests seem to reuse the @Mock annotation as a separate qualifier only, not the @Mock feature

Hmm, the test was added as part of #2780 which relates to the mock functionality.
It tests that you can manually override @Priority on it. Although you're right that this can be tested on any such annotation.
Plus I found one another test (in kafka extension) that actually uses @Mock so we don't completely stop testing it.
