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 hygienicIntro option
...
@Kha `hygienicIntro` is true by default. `hygienicIntro == false` is
the Lean3 behavior. If we find `hygienicIntro` too inconvenient in
practice, we set the default to false.

@Kha This is a first attempt to improve the error message for examples
