Adjust latencies and timeouts for dequeueing with HWS and consolidate them in one place. Make them longer to allow long running waves to complete without causing a timeout. The timeout is twice as long as the latency plus some buffer to make sure we don't detect a timeout prematurely. Change timeouts for dequeueing HQDs without HWS. KFD_UNMAP_LATENCY is more consistent with what the HWS does for user queues.
