This commit introduces initial AOT run-time support in the Spring
TestContext Framework.
- DefaultCacheAwareContextLoaderDelegate: when running in AOT mode, now
loads a test's ApplicationContext via the AotContextLoader SPI
instead of via the standard SmartContextLoader and ContextLoader SPIs.
- DependencyInjectionTestExecutionListener: when running in AOT mode,
now injects dependencies into a test instance using a local instance
of AutowiredAnnotationBeanPostProcessor instead of relying on
AutowireCapableBeanFactory support.
Closes gh-28205
