refactor: move String.ofList to the Prelude (#12029)

This PR moves `String.ofList` to `Init.Prelude`. It is a function that
the Lean kernel expects to be present and has special support for (when
reducing string literals). By moving this to `Init.Prelude`, all
declarations that are special to the kernel are in that single module.

(cherry picked from commit 9167b13afa3518556c1455172bf645e8216a197e

fix: bug `ite`/`dite` propagator used in `grind` (#11295)

This PR fixes a bug in the propagation rules for `ite` and `dite` used
in `grind`. The bug prevented equalities from being propagated to the
satellite solvers. Here is an example affected by this issue.

```lean
example
    [LE α] [LT α] [Std.IsLinearOrder α] [Std.LawfulOrderLT α]
    [Lean.Grind.CommRing α] [DecidableLE α] [Lean.Grind.OrderedRing α]
    (a b c : α) :
  (if a - b ≤ -(a - b) then -(a - b) else a - b) ≤
  ((if a - c ≤ -(a - c) then -(a - c) else a - c) + if c - d ≤ -(c - d) then -(c - d) else c - d) +
    if b - d ≤ -(b - d) then -(b - d) else b - d := by
