KIP-741 — Change default serde to be null

Accepted Kafka 3.0 Streams

Changes the default `DEFAULT_KEY_SERDE_CLASS_CONFIG` and `DEFAULT_VALUE_SERDE_CLASS_CONFIG` in `StreamsConfig` from `ByteArraySerde` to `null` in Kafka 3.0. The previous byte-array default silently accepted serialization mismatches, causing data corruption rather than an immediate configuration error when users forgot to specify a serde.
