testing/ostest: exercise custom work queues

Add a focused wqueue entry that exercises predefined and dynamically
created work queues without changing the no-argument ostest flow.

Share the semaphore wait and basic worker helpers across configurations.
Flat builds exercise scheduler queues, Protected builds exercise USRWORK,
and pthread-enabled builds additionally cover configurable custom worker
pools. When pthread support is disabled, only predefined USRWORK cases are
compiled.

Cover invalid arguments, priority lookup, immediate and delayed work,
pending replacement and cancellation, periodic requeue, synchronous and
parallel cancellation, concurrent queues, callback self-destruction, and
queue teardown.
