To apply `@ControllerAdvice` exception handling to non-controller
DataFetcher implementations like QueryDslDataFetcher,
QueryByExampleDataFetcher, and others, this commit exposes the
DataFetcherExceptionResolver from AnnotatedControllerConfigurer as a
bean. The existing auto-configured for DataFetcherExceptionResolver
then picks this up and passes it into the builder used to create the
GraphQlSource.
Closes gh-34526
