...by providing a non-inline key function for that class. This would have
prevented the issue that has been addressed by
2fe53b2e43 "Fix crash due to unexpected
dynamic_cast failures in optimized build", where a dynamic_cast to VCLXPopupMenu
failed on macOS (which uses pointer equivalence to determine RTTI equivalence),
because VCLXPopupMenu is final, so the compiler, at least in optimized builds,
just used a comparison between the object's recorded RTTI (from dylib A) against
the type's RTTI in dylib B, which erroneously failed.
