When audio_processing_fuzzer runs with 'DCHECK_ALWAYS_ON', it crashes when both AEC and AECM is enabled at the same time. This change detects that case and fixes https://clusterfuzz.com/v2/testcase-detail/6389429496446976. It also removes an unnecessary safeguard that didn't allow fuzzing with 8kHz input signals.
