dbt_debug: Generalize ERR_PRINT2 -> ERR_PRINT_IMPL w/ prefix param; Add IRQ_PRINT(.. "Interrupted" ), to clarify class of event.

An interruption might not be an error, but expected behavior - e.g. if a device is powered off.

Use IRQ_ERROR in GattHandler on:
- l2cap write error -> disconnect + exception
- l2cap nullptr reply (sendWithReply) -> disconnect + exception
- l2cap read error (l2capReaderThread) -> disconnect

We might find other occassions where this informal output fits.
