[tests] Accept GUIDs from .NET Framework in ccw-class-iface test. (#46150)
The commit
d5f338c088defdf81f4374f4e6fbff75c9b1e554 broke the ccw-class-iface test on Windows under .NET Framework. A couple of the tests expect Guid.Empty, but Mono only produces Guid.Empty because GUID generation isn't yet implemented for those classes.
This patch adds the values produced by .NET Framework as accepted values, while still accepting Guid.Empty for now.
