Generating Stubs (interop) for functions with int and short return types

[MHSchmidt]

VS 2019
VS Extension 1.17.0.13

When generating the stubs for interop assemblies with functions with return values of type int or short, entries are SetResult_int16_t or SetResult_in32_t in the ... mshl file. When using gcc 9.2.1, however, SetResult_INT16 or SetResult_INT32 must be created!
