* Test FreeRTOS trace facility functions. These following functions are enabled
* when configUSE_TRACE_FACILITY is defined 1 in FreeRTOS.
* Tasks: uxTaskGetTaskNumber(), uxTaskSetTaskNumber()
* Queues: ucQueueGetQueueType(), vQueueSetQueueNumber(), uxQueueGetQueueNumber()
* Event Groups: xEventGroupSetBitsFromISR(), xEventGroupClearBitsFromISR(), uxEventGroupGetNumber()
*
* Note: uxTaskGetSystemState() is tested in a separate unit test
