[audio][tas27xx] Add hardware metrics for error conditions

Add poll every 3 seconds and check for an error state of the codec.
Log potentially relevant codec state continuously.

Fixed: 82982
Test: tas27xx-test
Test: simulated error condition shows inspect data updated
Test: no error condition shows timer driven inspect updates a in:
