4848ad4869 feat: implement autoUnfold at simp 
Right now, it only supports the following kind of definitions
- Recursive definitions that support smart unfolding.
- Non-recursive definitions where the body is a match-expression. This
kind of definition is only unfolded if the match can be reduced.

2c7c7471db feat: add case' tactic for writing macros 
It is similar to `case` but does not admit goal in case of failure.
This is useful for writing macros.

6d926c7989 feat: macro expand match alternatives 
see #371

This commit does not implement all features discussed in this issue.
It has implemented it as a macro expansion. Thus, the following is
accepted
```lean
inductive StrOrNum where
  | S (s : String)
  | I (i : Int)

def StrOrNum.asString (x : StrOrNum) :=
  match x with
  | I a | S a => toString a
```
It may confuse the Lean LSP server. The `a` on `toString` shows the
information for the first alternative after expansion (i.e., `a` is an `Int`).
After expansion, we have
```
def StrOrNum.asString (x : StrOrNum) :=
  match x with
  | I a => toString a
  | S a => toString a
```
