Optimize `sort_batch` for single column case

### Is your feature request related to a problem or challenge?

`sort_batch` always uses multi column sort by sorting first to indices and then sorting the batch. See:

https://github.com/apache/datafusion/blob/ea788c72dddf24acd8dc8068cede939e11dfab84/datafusion/physical-plan/src/sorts/sort.rs#L628

We can use https://arrow.apache.org/rust/arrow/compute/fn.sort_limit.html instead

### Describe the solution you'd like

For single row case, sort the batch directly instead of sorting multiple columns.

### Describe alternatives you've considered

### Additional context

_No response_

Read datafusion/physical-plan/src/sorts/sort.rs around line 628 and the Arrow Rust sort_limit documentation. Confirm whether the request targets a single-column sort despite the body saying “single row,” then compare the direct path with the existing multi-column path and verify that sorting behavior is preserved.
