Nick Khyl 016ccae2da util/eventbus: add tests for a subscriber trying to acquire the same mutex as a publisher ...

As of 2025-11-20, publishing more events than the eventbus's
internal queues can hold may deadlock if a subscriber tries
to acquire a mutex that can also be held by a publisher.

This commit adds a test that demonstrates this deadlock,
and skips it until the bug is fixed.

Updates #17973
