chore(analysis/normed/group/basic): merge norm and semi_norm lemmas on prod and pi (#11492) norm and semi_norm are the same operator, so there is no need to have two sets of lemmas. As a result the elaborator needs a few hints for some applications of the pi lemmas, but this is par for the course for pi typeclass instances anyway.
