Changes the order of fixed and other properties in flatColumns

[ryantang247]

Fixes https://github.com/ant-design/ant-design/issues/51812

A similar issue can be found in the example from https://table-react-component.vercel.app/demo/fixed-columns-and-header-rtl, where Fix Left and Fix title3 should make the parent column fixed, but the child columns are not responding.

In the function mentioned, the property wasn't inherited due to misordering of the properties of column.

Walkthrough

本次更改调整了 flatColumns 函数中对子列（children columns）fixed 属性的赋值顺序。现在，父列的 fixed 属性会覆盖子列自身的 fixed 属性，从而确保当父列设置 fixed 时，其所有子列都能继承该固定属性。

Learning: 在 `src/Table.tsx` 文件的 React 组件 `Table` 中，即使 `bodyScrollLeft` 频繁更新，也需要在 `TableContextValue` 的 `useMemo` 依赖数组中包含 `bodyScrollLeft` 和 `headerCellRefs`，因为每次滚动时重新计算 `TableContextValue` 是解决该问题所必须的。

74-77: 修复继承逻辑，确保子列正确继承父列的固定属性

这个改动很好地解决了子列无法正确继承父列 fixed 属性的问题。通过将 fixed: parsedFixed 放在 ...subColum 之后，确保了父列的固定属性能够覆盖子列自身的固定属性，这符合预期的继承行为。

之前的实现中，子列的属性会覆盖父列的 fixed 属性，导致即使父列设置了 fixed，子列也可能不会表现为固定列。现在的实现确保了当父列设置为固定时，所有子列都会继承这个固定行为，这是更合理的默认行为。
