Implement IMAGE_WEAK_EXTERN_SEARCH_NOLIBRARY/LIBRARY characteristics flag.

Since COFFObjectFile class will set undefined flag for symbols with no alias flag, ORC ObjectFileInterface will not pull in this symbol. So, we only need to make sure the scope is local. NOLIBRARY and LIBRARY are handled in the same way for now. (which is what lld does right now)
