Use C11 alignas in pg_atomic_uint64 definitions
They were already using pg_attribute_aligned. This replaces that with
alignas and moves that into the required syntactic position. This
ends up making these three atomics implementations appear a bit more
consistent, but shouldn't change anything otherwise.
