GetObjectForNativeVariant throw InvalidCast ' Unable to case int to Intptr' on windows

Variant v = new Variant();
IntPtr pObj = Marshal.GetIUnknownForObject(new object());
IntPtr pNative = Marshal.AllocHGlobal(Marshal.SizeOf(v));
Marshal.GetNativeVariantForObject(pObj, pNative);
IntPtr pActualObj = Marshal.GetObjectForNativeVariant(pNative);

Merge pull request #4250 from yizhang82/nativevariant_fix

Fix GetObjectForNativeVariant test issue. It should roundtrip the actual object instead of IntPtr. Also add proper variant clean up code.

Fix #4192.
