ztest: add a weak implementation of test_main()

Browse source 
Introduce a weak implementation of test_main() which calls:
* ztest_run_registered_test_suites(NULL);
* ztest_verify_all_registered_test_suites_ran();

This will attempt to run all registered test suites and verify that
they each ran.

* When registering test suites, a pragma function can be provided to determine WHEN the test should
* run. It is possible that a test suite could be registered but the pragma always prevents it from
* running. In cases where a test should make sure that ALL suites ran at least once, this function
* may be called at the end of test_main(). It will cause the test to fail if any suite was
* registered but never ran.
