Sort or permute each 1D slice along an integer `dims` independently, matching Base. The default `dims=:` keeps the existing flat behaviour. There is no batched sort kernel, so each element is tagged with its slice and the whole array is sorted once by (slice, value), then scattered back into place. sortperm carries the original index as the payload and uses it to break ties, keeping the permutation stable. This reuses the backend's tuned sort and runs unchanged on CPU and every GPU backend.
