tests: Rework interrupt critical tests

This avoids test durations of more than one hour on fast targets, since
fast targets can count a lot during one clock tick period, so the minor
loop iteration count was quite high.  Estimate now the test body
duration to iterate only through the interesting time window.

Add and use interrupt_critical_section_test().
