  [ADT] Make ilist_select_iterator_type a type alias (NFC) (#160446)

Without this patch, we have:

  template <bool use_iterator_bits, typename Opts, bool arg1, bool arg2>
  struct ilist_select_iterator_type {
    using type = ...;
  }

This means that we must reference "type" with somewhat mouthful:

  typename ilist_select_iterator_type<...>::type

This patch simplifies the reference by making
ilist_select_iterator_type a type alias.

Now, we always obtain "bool use_iterator_bit" from
OptionsT::has_iterator_bits, so this patch folds the logic into the
type alias.
