KIP-671 — Introduce Kafka Streams Specific Uncaught Exception Handler

Accepted Kafka 2.8 Streams

Introduces a Kafka Streams-specific `StreamsUncaughtExceptionHandler` that receives uncaught exceptions from stream threads and returns one of `SHUTDOWN_STREAM_THREAD`, `REPLACE_STREAM_THREAD`, or `SHUTDOWN_CLIENT` to control recovery behavior. The existing Java `UncaughtExceptionHandler` fires after the thread is already dead, preventing in-thread recovery actions like graceful shutdown or thread replacement.
