feat: finish? tactic for grind interactive mode (#10837) 
This PR implements the `finish?` tactic for the `grind` interactive
mode. When it successfully closes the goal, it produces a code action
that allows the user to close the goal using explicit grind tactic
steps, i.e., without any search. It also makes explicit which solvers
have been used.

This is just the first version, we will add many "bells and whistles"
later. For example, `instantiate` steps will clearly show which theorems
have been instantiated.

Example:

```lean
/--
info: Try this:
  [apply] ⏎
    cases #b0f4
    next => cases #50fc
    next => cases #50fc <;> lia
-/
#guard_msgs in
example (p : Nat → Prop) (x y z w : Int) :
    (x = 1 ∨ x = 2) →
    (w = 1 ∨ w = 4) →
    (y = 1 ∨ (∃ x : Nat, y = 3 - x ∧ p x)) →
    (z = 1 ∨ z = 0) → x + y ≤ 6 := by
  grind => finish?
```

The anchors in the generated script are based on stable hash codes.
Moreover, users can hover over them to see the exact term used in the
case split. `grind?` will also be implemented using the new framework.
