fix: move Lean.List.toSMap to List.toSMap (#3035) 
This definition was clearly meant to be in the `List` namespace, but it
is also in a `namespace Lean` so it ended up as `Lean.List.toSMap`
instead of `List.toSMap`. It would be nice if #3031 made this
unnecessary, but for now this seems to be the convention.

I noticed this because of another side effect: it defines `Lean.List` as
a namespace, which means that
```lean
import Std

namespace Lean
open List

#check [1] <+ [2]
```
does not work as expected, it opens the `Lean.List` namespace instead of
the `List` namespace. Should there be a regression test to ensure that
the `Lean.List` namespace (and maybe others) are not accidentally
created? (Unfortunately this puts a bit of a damper on #3031.)
