Move IUnknown implementation to the separate files

IUnknown interface is used sometimes (e.g. in WinRT implementation of
wxNotificationMessage) alone, without other OLE routines, so it is
helpful to have its code in the separate file to avoid coupling with main
OLE code when only IUnknown implementation is required.
