This adjusts the runtime function declaration handling to track the owning module for the well known functions. This allows us to ensure that we are able to properly identify if the symbol should be imported or not when building the shared libraries. This will require a subsequent tweak to allow for checking for static library linkage to ensure that we do not mark the symbol as DLLImport when doing static linking.
