Replace the NormedAddCommGroup assumption with SemiNormedAddCommGroup where possible.

motivation: we need toDual, toDualMap etc. to define an InnerProductSpace instance for SeparationQuotient.

suggested in #16707.

Can you move

variable (𝕜 : Type*) (E : Type*)

outside the section so that you don't need to repeat it?
