Summary

This is a regression sometime between 0.48 and 0.58.

Given the following IDL file, compiled with midl + generated winmd, creating Rust bindings fails because the bindings refer to the HWND and HANDLE types which have not been imported or defined.

import "objidl.idl";

[ object, uuid(12345661-1223-1232-2233-134344444444), pointer_default(unique) ]
interface IAmAnInterface : IUnknown
{
    HRESULT PopWindow([in, unique] HWND parentWindow);
}

A minimal repro is attached. It requires nuget.exe in the path, available from nuget.org, and dotnet.exe (v.8) as well.
