Update `SpringBootContextLoader` so that it now implements the `AotContextLoader` interface. The `ContextLoaderHook` will abandon at `contextLoaded` if the test class is being AOT processed. This commit also introduces a new `AotApplicationContextInitializer` which allows us to plug-in an alternative AOT application context listener when the `SpringApplication` is running in test mode. Closes gh-31965
