This commit removes Boot's StreamBuilderFactoryBeanCustomizer and
updates KafkaStreamsAnnotationDrivenConfiguration to use
Kafka's StreamsBuilderFactoryBeanConfigurer instead of the
nested class KafkaStreamsFactoryBeanConfigurer.
This aligns more closely with how configuration is typically applied.
