feat: improve elabMatchAux
...
We now (try to) postpone `match ... with` elaboration when pattern
variables and patterns still contain metavariables before invoking `mkMatcher`.
This improvement makes sure we can elaborate an example submitted by
Daniel Selsam.
Remark: this update may create performance problems since we
backtrack `elabMatchTypeAndDiscrs` and `elabMatchAltView`.
We hope this is not a problem in practice since we use the "quick-check"
`waitExpectedTypeAndDiscrs`. Recall that we could compile Lean
without this commit. So, it suggests cases where we need to postpone
after `elabMatchAltView` are rare.

feat: add pp.safe_shadowing
...
When `pp.safe_shadowing` is set to true, we still use the
suggested name if the "body" does not contain a free variable with the
suggested name. This is the approach used in Lean 3, and I think it
improved the result in all affected tests.
The implementation was simple. The only nasty case was `delabAppMatch`.
The main motivation for this feature was hovering information such as
```lean
f : {α_1 : Type} → α_1 → α_1
```
when hovering over the `f` at
```lean
def g (α : Type) (a : α) :=
f a
```
With `safe_shadowing`, we get the nicer
```lean
f : {α : Type} → α → α
```

feat: add TermInfo for LVal
...
@Vtec234 Added the missing info.
Given
```lean
def f3 (s : Nat × Array (Array Nat)) : Array Nat :=
s.2[1].push s.1
```
We produce the following `InfoTree` for the body (originally at line 30)
```
Array.push (Array.getOp s.snd 1) s.fst : Array Nat @ ⟨30, 2⟩-⟨30, 17⟩
s : Nat × Array (Array Nat) @ ⟨30, 2⟩-⟨30, 3⟩
Prod.snd : {α β : Type} → α × β → β @ ⟨30, 4⟩-⟨30, 5⟩
Array.getOp : {α : Type} → [inst : Inhabited α] → Array α → Nat → α @ ⟨30, 5⟩-⟨30, 6⟩
1 : Nat @ ⟨30, 6⟩-⟨30, 7⟩
Array.push : {α : Type} → Array α → α → Array α @ ⟨30, 9⟩-⟨30, 13⟩
s.fst : Nat @ ⟨30, 14⟩-⟨30, 17⟩
s : Nat × Array (Array Nat) @ ⟨30, 14⟩-⟨30, 15⟩
Prod.fst : {α β : Type} → α × β → α @ ⟨30, 16⟩-⟨30, 17⟩

feat: store binder information in the InfoTree
...
@Vtec234 I am storing the binder information using `TermInfo`.
If it helps, I can add a custom `Info` constructor.
Example: `| Info.ofBinderInfo (i : BinderInfo)`.
