e020cd2ea0 refactor: parametrize over getConst : Name -> m (Option (ConstantInfo)) instead of env : Environment 
Motivation: when instatiating these templates, we can make definitions
opaque by returning `none` at `getConst`.

a087aea871 chore: remove special support for user-facing projection functions 
We now have kernel projections, and user-facing projection functions
are defined using them. So, we don't need special support anymore for
them. They are just regular functions in Lean4.

3faa033705 refactor: add parametric whnfCore 
Motivation: `WHNFUtil` will provide a parametric implementation for
WHNF. We will use it to implement `TypeUtil` and `matchPattern`.

e844a5be74 feat: simplify MetavarContext 
Remove `AbstractMetavarContext` and `TmpMetavarContext`.
Disable `TypeUtil` until we decide this is the right design.

Using very simple approach:
- No distinction betwen temporary and regular metavariables.
- Metavariables have a `depth` Nat field.
- MetavarContext also has a `depth` field.
- We bump the `MetavarContext` depth when we create a nested problem.
  Example: Elaborator (depth = 0) -> Simplifier matcher (depth = 1) -> TC (level = 2) -> TC (level = 3) -> ...
- When MetavarContext is at depth N, isDefEq does not assign variables from depth < N.
- Metavariables from depth N+1 must be fully assigned before we return to level N.
- New design even allows us to invoke tactics from TC.

1bf1290570 feat: use kernel projections in constructions 
Motivation: auxiliary recursors such as `brecOn` do not depend on
user-facing projection definitions anymore.
Thus, we can simplify `whnfCore` at `TypeUtil`.
