headers: Use EXTERN_GUID and DEFINE_PROPERTYKEY instead of a custom macro in mftransform.idl
These macros achieve exactly the same as the custom macro. That macro
was added in 84b180158009d4210f72d76e3888214dae045dab to avoid compiler
warnings - earlier d551b7d85ec63c0fa33f1a51ec5157722709fc53 tried to
fix the same warnings as well with a different setup. But these standard
macros that are used elsewhere already take care of the same issue.
