Add support of init and destroy methods 

This commit updates InitDestroyBeanPostProcessor so that it contributes
init or destroy method names to the `RootBeanDefinition`. This is then
used by the generator to provide these methods to the optimized AOT
context.

Invocation of those init methods still happen using reflection so
dedicated hints are contributed for them.

Closes gh-28151
