sapi: Add profiling report for tests
score: Delete _Watchdog_Report()

Delete _Watchdog_Report_chain().  These two functions use printk() with
thread dispatching and interrupts disabled.  So they are pretty useless
in real applications.  They are not part of the application APIs.  They
are only used in one test and do nothing useful in this test.
score: PR2174: Add workaround

Add _Scheduler_FIXME_thread_priority_queues_are_broken to prevent thread
priority queues in case an EDF scheduler is used.
