chore(field_theory/fixed): reuse existing mul_semiring_action.to_alg_hom by providing smul_comm_class (#8965) This removes fixed_points.to_alg_hom as this is really just a bundled form of mul_semiring_action.to_alg_hom + mul_semiring_action.to_alg_hom_injective, once we provide the missing smul_comm_class.
