We should improve Jackson2ObjectMapperBuilder by adding single entry alternatives to serializersByType(), deserializersByType(), and the new mixIns() that I will introduce with #16758.

For example in addition to serializersByType(Map<Class<?>, JsonSerializer<?>> serializers), we should add the following alternative serializerByType(Class<?> type, JsonSerializer<?> serializer) in order to make it easier to add 1 or 2 entries without creating a whole Map.
