re PR libstdc++/54005 (Use __atomic_always_lock_free in libstdc++ is_lock_free instead of __atomic_is_lock_free)

PR libstdc++-v3/54005
* include/bits/atomic_base.h (__atomic_base<_TTp>::is_lock_free(),
__atomic_base<_PTp*>::is_lock_free()): Call __atomic_always_lock_free
with the type-derived _S_alignment instead of __alignof the object.
* include/std/atomic (atomic<T>::is_lock_free()): Likewise.
