Andy Wilkinson 96eea1812d Fix WebSocketMessagingAutoConfiguration without a JsonMapper bean ...

Previously, if Jackson was on the classpath but no JsonMapper bean
was present, the app would fail to start. This commit updates
the auto-configuration so that the parts that require a JsonMapper
bean back of when no such bean is present.

The sample problem also exists with Jackson 2 and an ObjectMapper
bean. This commit also corrects that.

Fixes gh-49749
