    atoms: Make destructor explicit to prevent inlining
    
    The GjsAtoms destructor is giant because it calls a JS::Heap destructor
    for every atom. If it is generated implicitly, then GCC complains about
    it being too big to inline. Providing an explicit destructor seems to
    prevent this warning.
