BeanDefinitionRegistryRegisters a new singleton bean at runtime. This method expects that the bean definition data will have been compiled ahead of time.
If bean definition data is found the method will perform dependency injection on the instance followed by
invoking any PostConstruct hooks.
If no bean definition data is found the bean is registered as is.
