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

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.

@kha I'm not sure if this is the right fix. I just avoided the loop that adds
`mk_expr_placeholder` if the function is not a projection.
I didn't spend time investigating why we need `mk_proj_app`.
I know the library doesn't compile if we don't use it, and just use
```
return mk_app(copy_tag(ref, mk_constant(S_name + fname)), e);
```
