winhttp: name mangle class / iid on mingw Standard Windows type systems define CLSID_InternetSecurityManager and IID_IInternetSecurityManager, but MinGW lacks these definitions. As a result, we must hardcode these definitions ourselves. However, we should not use a public struct with those names, lest another library do the same thing and consumers cannot link to both.
