eCTS: Add task suite

Task A wakes up B and goes to sleep. Task B wakes up C then goes to
sleep. Task C wakes up A then goes to sleep. This is repeated
repeat_count times:

  A -> B -> C -> A -> ...

It's expected all tasks to run exactly repeat_count times. Tick task
runs to inject some irregularity.

eCTS: Test task priority

CTS task wakes up A and C then goes to sleep:

  CTS -> A, C -> A -> B -> C

Since C has a higher priority, C should run first. This should result
in C running one more time than A (or B).

eCTS: Add stack overflow test

This patch adds a test for stack overflow detection. CTS task tries
to overflow by calling a function recursively. This function sleeps
to incur context switch, where stack overflow is checked. Reboot is
expected but not checked.
