Add custom code generation for bean definition property values

This commits allows ValueCodeGenerator$Delegate implementations to be
loaded from `META-INF/spring/aot.factories` and considered for code
generation of bean definition property values. This default behavior
in DefaultBeanRegistrationCodeFragments can be customized as usual.

Closes gh-31427
