Spring @MockitoSpyBean does not support transparent verification

Overview

SpringAopBypassingVerificationStartedListener provides partial support for transparent verification for Mockito spies created via @MockitoSpyBean when the spy is wrapped in a Spring AOP proxy.

However, the following @Disabled test currently fails since the AOP proxy for the DateService is not considered a mock by Mockito.

https://github.com/spring-projects/spring-framework/blob/982f7f8f58a6368866559d969b5d4801557af2fd/spring-test/src/test/java/org/springframework/test/context/bean/override/mockito/MockitoSpyBeanAndAopProxyTests.java#L88-L117

To provide transparent verification support for @MockitoSpyBean, we need to implement and register a Mockito MockResolver, analogous to the SpringBootMockResolver in Spring Boot.

This unfortunately breaks code that doesn't have spring-aop on the classpath.
