freertos/make trace facility configurable

This commit makes configUSE_TRACE_FACILITY and
configUSE_STATS_FORMATTING_FUNCTIONS configurable in kconfig. Test cases fro the
functions enabled by the two configurations above have also been added.

Test cases for the following functions have been added...

- uxTaskGetSystemState()
- uxTaskGetTaskNumber()
- vTaskSetTaskNumber()

- xEventGroupClearBitsFromISR()
- xEventGroupSetBitsFromISR()
- uxEventGroupGetNumber()

- uxQueueGetQueueNumber()
- vQueueSetQueueNumber()
- ucQueueGetQueueType()

Test cases for the following functions were not required...

- prvListTaskWithinSingleList()
- prvWriteNameToBuffer()
- vTaskList()
