This updates the rw? tactic from Mathlib to use lazy discriminator trees and upstreams it.

Ah --- I was just noticing this while otherwise happily using rw_search to repair some proofs in Mathlib. There is a pretty unnecessary @ at the front of each lemma name here, because of the way we've going from Name to Expr. Do you see a way to avoid having this initial @?

Blind guess: use https://leanprover-community.github.io/mathlib4_docs/Std/Lean/Delaborator.html#Lean.ppConst in the right place?

@nomeata Thanks. I just tested it and it seems to work by upstreaming and inserting into Tactic.TryThis.addRewrite suggestion. I'll make a separate PR for it since it's largely orthogonal to this work.
