feat(algebra/order/monoid_lemmas_zero_lt): port some lemmas from algebra.order.monoid_lemmas (#12961) Although the names of these lemmas are from algebra.order.monoid_lemmas, many of the lemmas in algebra.order.monoid_lemmas have incorrect names, and some others may not be appropriate. Also, many lemmas are missing in algebra.order.monoid_lemmas. It may be necessary to make some renames and additions.
