chore: lemmas about BEq on List String.Slice (#13061) 
This PR adds lemmas about `BEq` on `List String.Slice`.

We show `(l == l') = false ↔ l.map copy ≠ l'.map copy` and deduce a
`BEq` version of the theorem about "intercalate-then-split":
```lean
theorem toList_split_intercalate_beq {c : Char} {l : List String} (hl : ∀ s ∈ l, c ∉ s.toList) :
    ((String.intercalate (String.singleton c) l).split c).toList ==
      if l = [] then ["".toSlice] else l.map String.toSlice
```
