a3642bd8d9 feat: add support for expanding let-declarations to simp 
Given a local context containing `x : t := e`,
`simp (config := { zeta := false }) [x]` will expand `x` even
if `zeta := false`.

3a13200772 refactor: add configuration options to control WHNF 
This commit also removes parameter `simpleReduce` from discrimination
trees, and take WHNF configuration options.
Reason: it is more dynamic now. For example, the simplifier
will be able to use different configurations for discrimination tree insertion
and retrieval. We need this feature to address issues #2669 and #2281

This commit also removes the dead Meta.Config field `zetaNonDep`.

This is an experimental new feature. We need more bells and whistles,
and `cbv` tactic for improving its performance.

`ApplyConfig.approx` (available in Lean 3), and sets it to true by

5f38a483f2 fix: congr tactic 
`MVarId.congr?` and `MVarId.hcongr?` should return `none` if an
exception is thrown while applying congruence theorem.

`MVarId.hcongr?` should try `eq_of_heq` before trying to apply
`hcongr` theorem.

closes #1787

BTW: Lean 4 `congr` tactic is applying `assumption`. Lean 3 version does not.
