refactor: move ppExpr to IO
...
@Kha I am also tracking `currNamespace` and `openDecls`.
BTW, I also tried an experiment where I added `currNamespace` and
`openDecls` to `Meta.Context`, but it looked weird. This information
is only needed in the elaborator and pretty printer.
The `PPContext` object should contain everything you need. You
can put `currNamespace` and `openDecls` in the `Delaborator.Context`.

fix: can't use maxPrec at by

If `by` uses `maxPrec`, then `have A by B ...` is parsed as
`have (A by B) ...` :(

feat: indented by
...
@Kha This one is not as useful as the indented `do`. When writing
interactive proofs I like the error message at the `}` showing the
resulting tactic state. We can simulate it using a `skip` in the end of the sequence :)
We remove the `skip` when the proof is done. Note that, the last `;`
is usually not part of the `by`. Example:
```lean
theorem ex (x y z : Nat) : y = z → y = x → x = z :=
fun _ _ =>
have x = y by apply Eq.symm; assumption; -- <<< the last `;` is part of the `have`
Eq.trans this (by assumption)
```

chore: change by precedence
...
@Kha it now uses the same precedence of `fun`.
The main motivation is to allow us to write `@by { ... }` instead of
`@(by { ... })`.
BTW, I am considering disabling implicit lambdas for `by ...` expressions.
It is automatically "intro"ducing the implicit variables without
giving an opportunity for users to pick their names.

Note that `?_` is not equivalent to `_`. Both do not have a name, but
`?_` is a synthetic metavariable which **cannot** be assigned by typing
constraints, and `_` is a regular metavariable.
We use `?_` to mark an anonymous hole that must be filled using tactics.
@Kha I will rename `namedHole` to `syntheticHole`
