Darian Leung 3e25d441a5 freertos: Add real time stats example
The following commit adds a real time stats example demonstrating how to
obtain task CPU usage statistics over a period of time, as opposed to the current
run time stats in FreeRTOS which measures task CPU usage as a percentage of
total system run time.
