d4f2bb77b8 feat(frontends/lean): recursive equation preprocessor
To make the equation compiler more convenient to use, we will add a
couple of preprocessing steps.
This commit adds the first one of them. In this step, we use
type inference to refine pattern variables, and we relax the
restrictions on inaccessible annotations.

We will also add a preprocessing step that implements the "complete
transition" step before we execute the elim_match step.

9afb53fad5 feat(kernel/expr): allow metavariables to have user-facing names
We need this feature for:
1) Defining nonlinear search patterns. Example: (?m <= ?m + 1)
2) Preprocessing recursive equations and support the pattern
refinement approach used in Agda. Example: in Agda, they accept
```
def append {A : Type} : Π (m n : nat), Vec A m -> Vec A n -> Vec A (m + n)
| m n nil            ys := ys
| m n (cons m' x xs) ys := cons x (append m' n xs ys)
```
These equations have to be refined. For example, `m` has to be
replaced with `0` (in the first equation), and `succ m'` in the
second. To implement this kind of refinement, we need to convert
the pattern variables (local constants) into metavariables during
elaboration. Then, the unassigned metavariables become local constants
again. This preprocessing step will fix some of the issues on #1594.
To completely fix #1594, we will need yet another preprocessing step
which will implement "complete transition" used in the equation
compiler before we start elim_match.cpp

9367e94900 fix(frontends/lean/pp): hide proof terms in non-proofs by default
This is mainly to reduce clutter.  Proof term printing can still be
forced using the `pp.proofs` option.

37d9e03cc1 feat(frontends/lean/pp): show substituted expressions for delayed abstractions
@leodemoura I tried to look up the unique names in the local context,
but this pretty much always fails.  AFAICT we never remember the local
context when pretty-printing expression texts.
