Retain it for earlier C standards and for C++ (as it still remains in C++23, albeit marked as deprecated since C17 and C++20.) Also separate `atomic_init` definitions from `ATOMIC_VAR_INIT` to avoid coupling with a deprecated initialisation mechanism. No functional change intended for `atomic_init`; this is purely a conformance and cleanup adjustment.
