Add native-image support for spring-rabbit

[mhalbritter]

When running the rabbitmq sample from spring-native in the sb-3.0.x branch (don't let the name fool you, it's NOT using spring native, but uses the AOT support from Spring Framework 6 and Spring Boot 3), the native image fails with this exception:

com.oracle.svm.core.jdk.UnsupportedFeatureError: Proxy class defined by interfaces [interface org.springframework.amqp.rabbit.connection.ChannelProxy] not found. Generating proxy classes at runtime is not supported. Proxy classes need to be defined at image build time by specifying the list of interfaces that they implement. To define proxy classes use -H:DynamicProxyConfigurationFiles=<comma-separated-config-files> and -H:DynamicProxyConfigurationResources=<comma-separated-config-resources> options.

I guess there are proxy hints missing.
