This commit provides the necessary infrastructure to let components
contribute statements that are used to fully instantiate a bean
instance.
To ease code generation, a dedicated infrastructure to register bean
definition is provided in the o.s.beans.factory.generator package.
BeanDefinitionRegistrar offers a builder style API that provides a way
to hide how injected elements are resolved at runtime and let
contributors provide code that may throw a checked exception.
BeanInstanceContributor is the interface that components can implement
to contribute to a bean instance setup. DefaultBeanInstanceGenerator
generates, for a particular bean definition, the necessary statements
to instantiate a bean.

Prior to this commit, GroovyDynamicElementReader was implemented in
Groovy, which required that developers have Groovy language support
installed and configured in their IDEs.
This commit ports GroovyDynamicElementReader from Groovy to Java,
making the compilation much simpler and allowing developers to open the
project in Eclipse or VSCode (or other IDEs without Groovy support)
without compiler errors.
This commit also converts related tests from Groovy to Java.
