Fix Crossgen2 compilation failures in several type generator tests (#51090)

As the PR

https://github.com/dotnet/runtime/pull/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

Tomas
