This PR implements parameters for the `instantiate` tactic in the
`grind` interactive mode. Users can now select both global and local
theorems. Local theorems are selected using anchors. It also adds the
`show_thms` tactic for displaying local theorems. Example:
```lean
example (as bs cs : Array α) (v₁ v₂ : α)
(i₁ i₂ j : Nat)
(h₁ : i₁ < as.size)
(h₂ : bs = as.set i₁ v₁)
(h₃ : i₂ < bs.size)
(h₃ : cs = bs.set i₂ v₂)
(h₄ : i₁ ≠ j ∧ i₂ ≠ j)
(h₅ : j < cs.size)
(h₆ : j < as.size)
: cs[j] = as[j] := by
grind =>
instantiate = Array.getElem_set
instantiate Array.getElem_set
```
