Revert "Revert "[Java] fix test hang occasionally when running FailureTest (#13934)" (#13992)"

Why are these changes needed?

Revert #13992. For some reason, workers hang when exiting the process. So I skipped std::atexit if it's on Windows. Here is the stack trace:

I also saw that test_atexit_handler is skipped on Windows. Maybe they are related.

@edoakes Do you have any insights on this?

@kfstorm sorry, not too familiar with std::atexit behavior. Looks like it's an issue with the completion queue cleanup in either the gRPC client or gRPC server though
