clr: Implement dynamic stream to HWq logic (#1958)

* clr: Implement dynamic stream to HW queue assignment

This change implements dynamic stream to hardware queue (HWq) mapping
with the following features:

* Queue depth heuristics with weights for optimal HWq assignment
* Make last used queue sticky for better locality
* Use pipe HWq to pipe mapping - gfx9 follows a round-robin queue to
  pipe mapping based on creation order (single process per device only,
  as pipe ID is statically assigned by runtime)
* More aggressive heuristic usage for better queue distribution
* Extend dynamic queues support for all stream priorities

Environment variables:
* DEBUG_HIP_DYNAMIC_QUEUE: 0 - disabled, 1 - Depth heuristics 2 -
  Depth+Pipe heuristics
* DEBUG_HIP_IGNORE_STREAM_PRIORITY=1: ignore priority stream creation

* clr: Clean up last_used_queue_
