feat(analysis/locally_convex): the topology of a locally convex space is generated by seminorms (#15035) This PR provides the proof that every locally convex space has a family of seminorms that induces the topology. This PR also adds a new simp-lemma is_R_or_C.real_norm, which calculates the norm of a real number r coerced into a is_R_or_C type as the norm of r. This made it necessary to change some proofs in a few places.
