…cal sort Correct the `EliminateSorts` follows: - If the upper sort is global then we can remove the global or local sort recursively. - If the upper sort is local then we can only remove the local sort recursively. If a global sort below locol sort, we should not remove the global sort becuase the output partitioning can be affected. This issue is going to worse since we pull out the V1 Write sort to logcial side. yes, bug fix add test Closes apache#37250 from ulysses-you/remove-sort.

### What changes were proposed in this pull request? Optimize Global sort to RepartitionByExpression, for example: ``` Sort local Sort local Sort global => RepartitionByExpression ``` ### Why are the changes needed? If a global sort below a local sort, the only meaningful thing is it's distribution. So this pr optimizes that global sort to RepartitionByExpression to save a local sort. ### Does this PR introduce _any_ user-facing change? no, only improve performance ### How was this patch tested? add test Closes apache#37330 from ulysses-you/optimize-sort.
