RFR: 7904036: jcstress: Enable annotation processors for all test projects

[Aleksey Shipilev]

[CODETOOLS-7904029](https://bugs.openjdk.org/browse/CODETOOLS-7904029) is incomplete.


$ java -jar tests-all/target/jcstress.jar -l | grep "All matching"
All matching tests - 158


Those are only the tests from jcstress-samples. We need to enable annotation processors for all tests projects.

For reference, compiled with JDK 17:


$ java -jar tests-all/target/jcstress.jar -l | grep "All matching"
All matching tests - 4552
