Instrospection API - addition

[jfedorov]

A ~month back I submitted this issue
Since that we moved to implementing device side profiling with Start/Stop in the middle of the application and realized that we need more information on the Command Queue.
For sure we need to know - if Queue is in-order or out-of-order. The other info - might be required - let's add it here for the completeness.
Can you, please, add three following APIs:

ze_result_t zeCommandQueueGetFlags(ze_command_queue_handle_t hCmdQueue, ze_command_queue_flags_t* pFlags)

ze_result_t zeCommandQueueGetMode(ze_command_queue_handle_t hCmdQueue, ze_command_queue_mode_t* pMode)

ze_result_t zeCommandQueueGetPriority(ze_command_queue_handle_t hCmdQueue, ze_command_queue_priority_t* pPriority)
