KIP-828 — Add the corresponding validator to the configuration where the validator is missing

Discussion Kafka 3.3 Admin

Adds missing validators to configuration parameters across AdminClientConfig, ConsumerConfig, ProducerConfig, SaslConfigs, and broker configs (e.g., NonNullValidator for serializer/deserializer classes, valid-value checks for security.protocol, compression.type, ssl.client.auth). Without validators, invalid values for these configs are only discovered at runtime when the misconfigured component attempts to use them.
