SWDEV-68792 - [OpenCL][HWS/CWSR] Adding support for Hardware Scheduler and Compute Wave Save restore (CWSR) feature on ORCA

	Adding a temporary w/a for a CP uCode bug in HWS mode. Due to this bug, CP uCode loops through a RUNLIST unless there is a submission on all queues in HWS mode. This causes some overhead and performance drop in PCMark8 on CZ in HWS mode. To work around this issue, it was suggested to submit a dummy packet during initialization on all available queues on HWS mode so that CP uCode can break the loop. This w/a should be removed once CP uCode provides a final fix for this issue.
