Add a `@JsonComponent` annotation that can be used to indicate that a Bean is a JsonSerializer and/or JsonDeserializer that should be registered with Jackson. Support is provide via a new `JsonComponentModule` which is auto-configured in `JacksonAutoConfiguration`. Also add `JsonObjectSerializer` and `JsonObjectDeserializer` classes which provided as a convenient base for serializers that work with Objects. Fixes gh-3898
