  CL/Vulkan: Implement cl_khr_priority_hints
  
  cl::CommandQueue contains queue priority from
  clCreateCommandQueueWithProperties.
  Similar to EGL_IMG_context_priority, a queue with a pre-assigned
  priority is selected when submission.
  
  Bug: angleproject:433980937
  Tests-Passing: OCLCTS.test_api queue_hint
