Slawomir Milczarek 7334aee8a8 fix: Switch copy-engine idle check to try-lock ...

Related-To: NEO-13325

Replace blocking obtainUniqueOwnership with non-blocking
tryObtainUniqueOwnership in isCopyEngineOnDeviceIdle.
Treat copy engine as not idle when lock is contended
(conservative; prevents false stops).
Avoid deadlock scenarios caused by holding
directSubmissionsMutex while waiting on a CSR lock.
