KAFKA-18053 Clean up topology config

[sebastienviale]

Pull request to implement KIP-1138, which aims to address several issues related to the configuration application process in Kafka Streams.

This PR has multiple goals:

• Deprecate TopologyConfig in favor of StreamsConfig.

• Deprecate StreamsBuilder#build(StreamsConfig) and encourage users to pass configurations via the StreamsBuilder constructor instead.

• Deprecate constructors in StreamsBuilder and Topology that accept a TopologyConfig, replacing them with constructors that accept a Properties or Map.

• Improve misconfiguration detection by:

  • Throwing an exception if a topology-specific config is set in StreamsConfig but not applied to the topology.
  • Logging a warning if a topology-specific config is set in both places but has different values.
