Support Mockito with @MockBean and @SpyBean in AOT-processed tests

[philwebb]

Currently Mockito doesn't work with native tests. See spring-attic/spring-native#1561 and spring-attic/spring-native#1063 for more details.

For now, we can disable the ResetMocksTestExecutionListener, but it would be nice if we could make Mockito work.

FYI there is ongoing work on GraalVM side to make it work, I will try to share up to date news about current status.

There's more than just GraalVM supporting this. Currently, using @MockBean wreaks havoc even when not using native-image, just enabling AOT mode is enough.

We have a smoke test which uses @MockBean here: https://github.com/spring-projects/spring-aot-smoke-tests/tree/main/boot/boot-tcf

I've added metadata for Mockito 4.8.1 to the reachability-metadata repository. However I found no way to get the class mocks from Mockito working, as they all rely on creating classes at runtime. But it works when using the ProxyMockMaker, which is able to mock interfaces.

@mhalbritter are there plans to support @MockBean? Having this with the proxymockmaker would be already a big gain.
