Subject: fixes #21353; fixes default closure in the VM (#24070)

fixes #21353

```nim
  result = newNodeIT(nkTupleConstr, info, t)
  result.add(newNodeIT(nkNilLit, info, t))
  result.add(newNodeIT(nkNilLit, info, t))
```
The old implementation uses `t` which is the type of the closure
function as its type. It is not correct and generates ((nil, nil), (nil,
nil)) for `default(closures)`. This PR creates `(tyPointer, tyPointer)`
for fake closure types just like what cctypes do.
