feat: replace OS-specific stream redirection with pure-Lean Stream redirection
...
This avoids the temporary files workaround on macOS and Windows, and makes sure
we can process a `#eval` command and write messages to stdout at the same time.

feat: real ST monad
...
@Kha: the new `ST` (and `EST`) are escapable like the Haskell ST monad.
It makes `StateRefT` much more useful because we can now run it from pure
code.

feat: give a name to EIO Empty
...
@Kha I am calling it `ST` for lack of a better name. It makes some
sense since only the `IO.Ref` operations are in `EIO Empty` :)
That being said, it may confuse Haskell users.
BTW, I had to give the name to avoid a nontermination in the TC
procedure when using
```lean
instance EIOEmpty.monadLift {ε} : HasMonadLift (EIO Empty) (EIO ε) :=
{ monadLift := fun α => fromEmptyEIO }
```

feat: remove IO.ref.reset
...
`reset` was used to implement a "buggy" `IO.ref.modify`.
```lean
@[inline] def Ref.modify {α : Type} (r : Ref α) (f : α → α) : m Unit := do
v ← r.get;
r.reset;
r.set (f v)
```
`IO.Ref.reset` will store a nullptr in `r`.
Now, suppose another thread tries to read this reference,
it will get an `IO.error`.
It is not a crash, but it is really weird behavior.
