[Macros on Darwin] Use device platform paths when building for the simulator To avoid having duplicated macro implementations in both the device and simulator platforms, when building for a simulator platform, pass `-external-plugin-path` that points into the *device* platform. There is no need to have macro implementations in the simulator platforms. Implements rdar://112563655.
