If `Alloc::propagate_on_container_move_assignment` exists and `Alloc::propagate_on_container_move_assignment::value` is `true`, the allocator is overwritten, if not the moved elements are created using the existing allocator.
If如果 `Alloc::propagate_on_container_move_assignment` exists and存在且 `Alloc::propagate_on_container_move_assignment::value` is为 `true`, the allocator is overwritten, if not the moved elements are created using the existing allocator.，则分配器会被覆盖；否则，移动的元素将使用现有的分配器创建。
