    c++: Propagate attributes to clones in duplicate_decls [PR67453]

    On the following testcase where the cdtor attributes aren't on the
    in-class declaration but on an out-of-class definition, the cdtors
    have their clones created from the in-class declaration, and later on
    duplicate_decls updates attributes on the abstract cdtors, but nothing
    propagates them to the clones.
