Spy and Mock of EO, dummies or other WO classes does not works under Mockito 5.x

[spelletier]

By default Mockito 5.x use a new MockMaker that is not compatible with any WO subclasses. It is still possible to create mock and spy by specifying the old MockMaker like this:

• Replacing @mock with @mock(mockMaker = MockMakers.SUBCLASS) in field declaration;
• Replacing mock(...) with mock(..., withSettings().mockMaker(MockMakers.SUBCLASS));
• Replacing spy(instance) with instance = mock(InstanceClass.class, withSettings()
  .mockMaker(MockMakers.SUBCLASS)
  .spiedInstance(instance).defaultAnswer(CALLS_REAL_METHODS));

I suggest to adjust the wounits behaviour when detecting @SPY annotation to specify the old MockMaker and creating a new @EOMock (or WOMock) annotation to help creating compatible mock with the old MockMaker.

I have a local working version with the @SPY fix but the MockMakers is new and require Mockito 4.8.

I experience no problems using Mockito 4.x. Maybe we can upgrade the Mockito dependency to 4.8 and adjust code to be compatible with 5.x.

I has to adjust some test code to remove warnings and some error, especially in assert call that changed style.
