Support Protobuf serialization in WebFlux
This commit introduces Protobuf support in WebFlux via dedicated codecs. Flux<Message> are serialized/deserialized using delimited Protobuf messages with the size of each message specified before the message itself. In that case, a "delimited=true" parameter is added to the content type. Mono<Message> are expected to use regular Protobuf message format (without the size prepended before the message). Related HttpMessageReader/Writer are automatically registered when the "com.google.protobuf:protobuf-java" library is detected in the classpath, and can be customized easily if needed via CodecConfigurer, for example to specify protocol extensions via the ExtensionRegistry based constructors. Both "application/x-protobuf" and "application/octet-stream" mime types are supported. Issue: SPR-15776
