PSCreateMemoryPropertyStore out param should be [ComPtr]

[jevansaks]

This method clearly returns a COM object but isn't [ComPtr] so CsWin32 doesn't promote it to an "object" out param as it would for COM parameters.

public unsafe static extern HRESULT PSCreateMemoryPropertyStore([In][Const] Guid* riid, [Out] void** ppv);

ppv needs [ComPtr] too.
