feat: encode let_fun using a letFun function (#2973) 
Switches from encoding `let_fun` using an annotated `(fun x : t => b) v`
expression to a function application `letFun v (fun x : t => b)`.

feat: pp.beta to apply beta reduction when pretty printing (#2864) 
This was a Lean 3 pretty printer option. While this pretty printer
option tends to lead to confusing situations when set, it has been
frequently requested. [It is
possible](https://github.com/leanprover-community/mathlib4/pull/7910) to
implement this pretty printer option as a user, but it comes with some
artifacts -- for instance, expressions in hovers are not beta reduced.
Adding this as a core pp option is cleanest.

(We should consider having hooks into the tactic evaluator to allow
users to transform the tactic state between tactics. This would enable
beta reducing the entire local context for real, which would be useful
for teaching.)

Closes #715

76a7754d08 fix: have parenthesizer copy source info to parenthesized term 
This causes the info view to have the entire parenthesized expression be hoverable.

10a56bf4a1 fix: fixes #1571 
The previous implementation was using the following heuristic
```lean
      -- heuristic: use non-dependent arrows only if possible for whole group to avoid
      -- noisy mix like `(α : Type) → Type → (γ : Type) → ...`.
      let dependent := curNames.any fun n => hasIdent n.getId stxBody
```
The result produced by this heuristic was **not** producing an
accidental name capture, but I agree
it was confusing to have `∀ (a : True), ∃ a, a = a : Prop` instead of
`True → ∃ a, a = a : Prop` since there is no dependency.
AFAICT, all examples affected by this commit have a better output now.
