audio: cadence: add optional API error reporting

Extend cadence_codec_process_data() with an optional output parameter
for returning Cadence API error codes while preserving existing return
behavior: non-fatal API errors still return 0 and fatal errors are
returned.

Suppress non-fatal warning prints in this path and add lightweight
overwrite tracing for repeated API error updates.

Update cadence IPC3 and IPC4 call sites to pass NULL for now.
