IPortableDevice types being generated with in keywords

[wadebader]

Actual behavior

Some PortableDevice related COM interfaces are generated with inaccurate method signatures. Everything still works, but I don't think this is correctly generated. For example:

internal interface IPortableDevicePropVariantCollection
{
    void GetCount(in uint pcElems);
    ...
    void GetAt(uint dwIndex, in winmdroot.System.Com.StructuredStorage.PROPVARIANT pValue);
}

I've found the same behavior on IPortableDevicePropVariantCollection, IPortableDeviceKeyCollection, IPortableDeviceValues, and IPortableDeviceValuesCollection.

Expected behavior

For all of those methods, I would expect the data to be returned to me to use an out parameter rather than an in parameter.
