Fix Crossgen2 compilation failures in several type generator tests

As the PR

#44041

effectively decoupled OwningType from Method in MethodWithToken,
I believe we now need to include OwningType in the Equals check,
otherwise we may (and sometimes do) crash in the assertion failure
checking that OwningType matches between instances.

Thanks
