Ioannis Glaropoulos f3f3dc8768 tests: kernel: fatal: run test for ARMv8-M with MPU stack guards 
HW stack protection in ARMv8-M is implemented by default
with the built-in stack guard mechanism. Therefore, by
default all tests for ARMv8-M will use the built-in stack
overflow mechanism (CONFIG_BUILTIN_STACK_GUARD is set in
tests). However, we would like have some coverage on the
MPU stack guard mechanism for ARMv8-M. The added test case
manually disables BUILTIN_STACK_GUARD and enables the
MPU_STACK_GUARD option, to provide that test coverage.

README 

This test case verifies that kernel fatal error handling works correctly.

If a thread causes a CPU exception, and it is not in an ISR or "essential"
thread, the thread gets aborted and the rest of the system executes normally.
