[extraction] Fix #7191: Avoid unsound eta-reduction
`Mlutil.simpl` and `Mlutil.atomic_eta_red` did some unsound eta-reductions as
follows:
(fun x0 ... xn => MLexn x0 ... xn) ->eta MLexn.
`MLexn` raises an exception thus is not a value in OCaml. So the above
simplification may change the behavior of extracted programs. This patch
restricts `atomic_eta_red` to eta-redexes whose core is both atomic and value.
