We must no pre-specialize imported code (except if this was explicitly called for by the importing module). Therefore, don't pre-specialize `shared` definitions based on their pre-specialization attributes. Rather, only pre-specialize if the pre-specialization is called for using a `target: "theFunctionToSpecialize"` parameter. Run OnonePrespecializations before serialization so that module native functions are not yet marked `shared` and can be identified as native. rdar://92337361
