Add autoconfiguration for AcknowledgementResultCallback components

[tomazfernandes]

What: Add auto-configuration for AcknowledgementResultCallback and AsyncAcknowledgementResultCallback in the default SQS listener container factory.

Why: We already auto-configure MessageInterceptor(s) and ErrorHandler (blocking + async). The callbacks are the remaining extension points that still require manual wiring.

Where: SqsAutoConfiguration#defaultSqsListenerContainerFactory

spring-cloud-aws/spring-cloud-aws-autoconfigure/src/main/java/io/awspring/cloud/autoconfigure/sqs/SqsAutoConfiguration.java

Lines 119 to 145 in 88417a0

	public SqsMessageListenerContainerFactory<Object> defaultSqsListenerContainerFactory(
	ObjectProvider<SqsAsyncClient> sqsAsyncClient, ObjectProvider<AsyncErrorHandler<Object>> asyncErrorHandler,
	ObjectProvider<ErrorHandler<Object>> errorHandler,
	ObjectProvider<AsyncMessageInterceptor<Object>> asyncInterceptors,
	ObjectProvider<ObservationRegistry> observationRegistry,
	ObjectProvider<SqsListenerObservation.Convention> observationConventionProvider,
	ObjectProvider<MessageInterceptor<Object>> interceptors,
	ObjectProvider<JacksonMessageConverterMigration> messageConverterFactory,
	MessagingMessageConverter<?> messagingMessageConverter) {
	SqsMessageListenerContainerFactory<Object> factory = new SqsMessageListenerContainerFactory<>();
	factory.configure(this::configureProperties);
	sqsAsyncClient.ifAvailable(factory::setSqsAsyncClient);
	asyncErrorHandler.ifAvailable(factory::setErrorHandler);
	errorHandler.ifAvailable(factory::setErrorHandler);
	interceptors.forEach(factory::addMessageInterceptor);
	asyncInterceptors.forEach(factory::addMessageInterceptor);
	messageConverterFactory.ifAvailable(mcf -> mcf.configureLegacyObjectMapper(messagingMessageConverter));
	if (this.sqsProperties.isObservationEnabled()) {
	observationRegistry
	.ifAvailable(registry -> factory.configure(options -> options.observationRegistry(registry)));
	observationConventionProvider
	.ifAvailable(convention -> factory.configure(options -> options.observationConvention(convention)));
	}
	factory.configure(options -> options.messageConverter(messagingMessageConverter));
	return factory;
	}

Tests: Add or update tests to cover both callback variants and their absence.
