dumpcpp silently generates uncompilable files for some .NET libraries

Steps to reproduce

1. Run dumpcpp on the attached .tlb file (taken from the IPC-CFX SDK [1][2])
2. #include the generated .h file in a Hello World project
3. Try to build the project

Outcome

The build fails because the generated file contains numerous undeclared types (ICloneable, ISerializable, IDisposable, IEnumerable, IList, ICollection, and _Attribute)

Suggestion

Patch dumpcpp to make these types work properly.

If these types are not supported for whatever reason, it would be good if dumpcpp reports this while generating the C++ code.
