Mike Hommey 4856fd3c1e Bug 1893553 - Remove unused broken code from cctools. r=firefox-build-system-reviewers,sergesanspaille,nalexander
The base class doesn't have a clone member function, so the code was
never valid. As it was unused, that didn't cause problems until clang
caught this earlier than instantiation in
https://github.com/llvm/llvm-project/pull/84050
