Add a way to register the need for runtime reflection, resources, proxying, and serialization on components

[snicoll]

Spring Native has a component called NativeConfigurationRegistry that offers a programmatic API to register the need for reflection, resources that are to be shipped in the native image, proxies as well as classes that should be Serializable.

We'd like to revisit this contract and make less native specific as we believe that such information could be useful elsewhere.

Such an infrastructure could land in spring-core as it is rather high-level and focused on classes and resources. The actual processing of the registry, for instance, to write GraalVM-specific configuration files is not in the scope of this issue.
