ztest: Safely handle fail/skip/pass outside tests

Browse source 
Updates the implementation when KERNEL is available to safely bail on
the test when the test calls fail, skip, or pass during invalid test
phases. Print a detailed message, and skip all other tests. The test
run will be marked as failed.
