refactor: replace sort.Strings with slices.Sort (#23457)

The slices package provides type-safe generic replacements for the
old typed sort convenience functions. The codebase already uses
slices.Sort in 43 call sites; this finishes the migration for the
remaining 29.

- sort.Strings(x)          -> slices.Sort(x)
- sort.Float64s(x)         -> slices.Sort(x)
- sort.StringsAreSorted(x) -> slices.IsSorted(x)
