520a5f566a fix: local name resolution 
Local name resolution was incorrect when identifier had macro scopes
and projections were used.

98dbe45ab8 chore: remove Monad List instance 
@Kha The new `do` notation works for pure code too.
It automatically inserts `Id` if the expected type is not a monad.
This works great when we are not conflating data and control.
After deleting `Monad List`, we will be able to write functions such as
```lean
def mapWhen (p : Nat → Bool) (f : Nat → Nat) (xs : List Nat) : List Nat := do
for x in xs do
  if p x then
    x := f x
```
without adding `Id.run` before the `do`.

d0ade7ff08 feat: extend doBlock expander 
- Add support for `if h:c then t else e`, `h` may shadow reassignable
variables

- Pattern variables in `match` alternatives may shadow reassignable
variables

- A single declaration/reassignment in a `do` block may
declare/reassign multiple variables. Example: `let (x, y) := t`
