aaudio: Improve consistency with CDD

1) Skip certain tests if the device doesn't support the corresponding feature:
   - skip tests that open output streams on devices that don't have output;
   - skip tests that open input streams on devices that don't have mic.

2) Do not fail tests if the measured latency is too high, only issue
   a warning.
