This commit improves on the bean overriding feature in several ways: the API is simplified and polished (metadata and processor contracts, etc...). The commit also reworks infrastructure classes (context customizer, test execution listener, BeanOverrideBeanFactoryPostProcessor, etc...). Parsing of annotations is now fully stateless. In order to avoid OverrideMetadata in bean definition and to make a first step towards AOT support, the BeanOverrideBeanFactoryPostProcessor now delegates to a BeanOverrideRegistrar to track classes to parse, the metadata-related state as well as for the field injection methods for tests. Lastly, this commit increases the test coverage for the provided annotations and adds integration tests and fixes a few `@TestBean` issues.
