The derive attribute has historically been problematic, mostly because it can be very slow, but improvements over the last few years have improved its performance to the point where we can begin to use it more liberally in the windows crate without impacting build time. This update limits use of the derive attribute to COM interfaces as a start. Applying it to structs continues to be a little problematic, but it seems worthwhile to at least simplify things in degrees.

More use of derive is great, if only because it can substantially reduce the lines of code (something e.g. IDEs complain about).
