Felipe Neves 77bf1ff1c0 freertos/tests: added test to evaluate scheduling time
freertos/Kconfig: fix trailing space on optimized scheduler option

freertos/tests: moved test context variables inside of test task.

The public variables used on scheduling time test now were packed into a structure allocated on  test case task stack and passed to tasks as arguments saving RAM comsumption.
