Carles Cufi cb0cf9f5f4 kernel: profiling: Expose an API call to analyze call stacks 
The main, idle, interrupt and workqueue call stack definitions are not available
to applications to call stack_analyze() on, but they often require to be
measured empirically to tune their sizes in particular applications and
use cases.
This exposes a new k_call_stacks_analyze() API call that allows the
application to measure the used call stack space for the 4
kernel-defined call stacks.
Additionally for the ARC architecture the FIRQ stack is also profiled.
