   After a bit of research it seems that no implementation in Mesa actually respects pQueuePriorities; therefore I have reverted that part of the change. We might want to revisit this in the future.
   
   As for VkQueueGlobalPriorityEXT, it's mostly meant for real-time use cases that requires GPU preemption, e.g. compositors, and requires process privileges for any higher-than-normal priority settings. Since most TVM workload is non-interactive, it's better to just not use it, or even if we use it, we would set the priority to LOW.
