Description
## Enhancement
We have many place to use the ```exp/slices``` to sort our struct. It can improve performance by using pdqsort and clean branch check. But We have many placement using the old ```sort```. Please remove it. Here is [the example ](https://github.com/pingcap/tidb/pull/34404).
BTW, You haven't to change the ```bazel.build```. it can be updated by robot.
