refactor: Add MkMatcherInput.
...
Since we are going to make `mkMatcher` reversible, it's quite useful to have the input be a `structure`. This way we make sure, that the inverse function always returns the same type as `mkMatcher` needs as input.

refactor: add MonadBacktrack
...
The new class specifies an interface for saving and restoring the
backtrackable part of the state.
This commit also fixes a few issues.
- `commitWhen` at `LevelDefEq` was defining a checkpoint for
the `isDefEq` methods, and it affects how postponed universe
constraints are handled. However, the name suggests it is
similar to `commitWhenSome?`, and consequently it was used
in other places that had nothing to do with `isDefEq`.
So, I renamed it, and provided the generic `commitWhen` at the new
`MonadBacktrack.lean` file.
- We were restoring more state then needed in a few places.
For example, we were discarding all caches.
- At `SyntheticMVars.lean`, we were using the `Meta.commitWhenSome?`
method which does not restore the `Term.State`.

If generated type is not correct, we should abort "discriminant

fix: disable implicit-lambdas when elaborating patterns
...
@Kha, Jason's example on issue #337 suggests that injecting
implicit-lambdas while elaborating patterns is problematic.
The elaborator was injecting `fun {Γ} =>` before the
pattern variable `ftm`.
So, I disabled the implicit-lambda during pattern elaboration. I
didn't find an example where it would be useful.
