7b6732a137 refactor: ExprDefEq.lean and LevelDefEq.lean are now implementation only files 
We use the export/extern idiom to define `isLevelDefEqAux`, and then
define the `isDefEq` user facing functions at `Meta/Basic.lean`.

They are array versions of `withLocalDecl` and `withLocalDeclD`, respectively. They are useful when you need to create variables dynamically.

2694e7798a 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`.

@Kha I marked the corresponding methods as `protected`.
I currently can't stand `throw_error`, and I am optimistic about
server highlighting feature you are working on :)
