Timothy Flynn d9c2447999 AK: Add free function to wrap around __atomic_is_lock_free built-in ...

Note: this exact implementation is needed for __atomic_is_lock_free to
link with both GCC (for the SerenityOS build) and Clang (for the Fuzzer
build). The size argument must be a compile-time constant, otherwise it
fails to link with both compilers. Alternatively, the following
definition links with GCC but fails with Clang:

    template<size_t S>
    static inline bool atomic_is_lock_free(volatile void* ptr = nullptr)
    {
        return __atomic_is_lock_free(S, ptr);
    }
