Subject: [PATCH] GH-8697: No autowire for Int ConversionService

Fixes https://github.com/spring-projects/spring-integration/issues/8697

The `IntegrationUtils.INTEGRATION_CONVERSION_SERVICE_BEAN_NAME` is not designed
for end-user code autowire, rather internal framework requirement

* Mark `BeanDefinition` for `IntegrationUtils.INTEGRATION_CONVERSION_SERVICE_BEAN_NAME`
as `setAutowireCandidate(false)`
