chore(order/iterate): generalize lemmas about inequalities and iterations (#5357) If f : α → α is a monotone function and x y : ℕ → α are two sequences such that x 0 ≤ y 0, x (n + 1) ≤ f (x n), and f (y n) ≤ y (n + 1), then x n ≤ y n. This lemma (and its versions for <) generalize geom_le as well as iterate_le_of_map_le.
