Fix test-specific configuration metadata

Most of the config keys defined by the `spring-boot-test-autoconfigure` module can't be overridden because they are mapped with `@PropertyMapping` on an annotation. It is confusing that such keys are exposed in content assistance as using them will have no effect. This commit removes the annotation processor from the build so that the `@ConfigurationProperties` beans aren't processed anymore. Instead, manual metadata is written for the two only keys that are effectively used in regular configuration. As a result, the `additional-spring-configuration-metadata` file has been renamed to `spring-configuration-metadata` since nothing is processing it anymore. Closes spring-projectsgh-7887
