chore: DiscrTree helper functions (#3303) 
`DiscrTree` helper functions from `Std`, used in `ext`, `exact?`, and
`aesop`.

(There are a few more to follow later, with other Std dependencies.)

doc: implicit type arguments are indexed in the discrtree (#3301) 
A small fix to the `DiscrTree` documentation to reflect the fact that
implicit type arguments *are* indexed and do not become `star` or
`other`. The following is a reproduction:
```lean
import Lean
open Lean Meta Elab Tactic

elab "test_tac" t:term : tactic => do
  Tactic.withMainContext do
    let e ← Term.elabTerm t none
    let a : DiscrTree Nat ← DiscrTree.empty.insert e 1 {}
    logInfo m!"{a}"

example (α : Type) (ringAdd : Add α) : True := by
  /- (Add.add => (node (Nat => (node (* => (node (0 => (node (1 => (node #[1])))))))))) -/
  test_tac @Add.add Nat instAddNat 0 1
  /- (Add.add => (node (_uniq.1154 => (node (* => (node (◾ => (node (◾ => (node #[1])))))))))) -/
  test_tac @Add.add α ringAdd ?_ ?_
```

3a13200772 refactor: add configuration options to control WHNF 
This commit also removes parameter `simpleReduce` from discrimination
trees, and take WHNF configuration options.
Reason: it is more dynamic now. For example, the simplifier
will be able to use different configurations for discrimination tree insertion
and retrieval. We need this feature to address issues #2669 and #2281

This commit also removes the dead Meta.Config field `zetaNonDep`.
