feat: add bitwise operations to reduceNat? and kernel (#3134) 
This adds bitwise operations to reduceNat? and the kernel. It
incorporates some basic test cases to validate the correct operations
are associated.

fix: reduceNat? match terms with free or meta variables (#3139) 
This removes checks in `Lean.Meta.reduceNat?` that caused it to fail on
terms it could handle because they contain meta variables in arguments.
This lead to those operations being reduced using their equational
definitions and slow performance on large patterns:

```
set_option profiler true
set_option profiler.threshold 1

def testMod (x:Nat) :=
  match x with
  | 128 % 1024 => true
  | _ => false
-- elaboration took 3.02ms

def testMul (x:Nat) :=
  match x with
  | 128 * 1 => true
  | _ => false
-- type checking took 11.1ms
-- compilation of testMul.match_1 took 313ms
-- compilation of testMul took 65.7ms
-- elaboration took 58.9ms
```

Performance is slower on `testMul` than `testMod` because `whnf` ends up
evaluateing `128 * 1` using Peano arithmetic while `128 % 1024` is able
to avoid that treatment since `128 < 1024`.

272dd5533f chore: style use · instead of . for lambda dot notation 
We are considering removing `.` as an alternative for `·` in the
lambda dot notation (e.g., `(·+·)`).
Reasons:
- `.` is not a perfect replacement for `·` (e.g., `(·.insert ·)`)
- `.` is too overloaded: `(f.x)` and `(f .x)` and `(f . x)`. We want to keep the first two.

This is a set of examples that exposes problems with the old frontend
elaborator. These issues have been fixed in the new frontend.

@dselsam The good news is that the problem is fixable.
I included a workaround `mergeCongr3` for avoiding the overhead in the current system.
