This adds some instances regarding normed algebra structures to RestrictScalars to mimic those for normed spaces.

In addition, given a normed -algebra, this puts a normed -algebra structure on the same space. This is not adding any new data instances, as these already exist from Algebra.complexToReal.

This adds some instances regarding normed algebra structures to `RestrictScalars` to mimic those for normed spaces.

In addition, given a normed `ℂ`-algebra, this puts a normed `ℝ`-algebra structure on the same space. This is *not* adding any new data instances, as these already exist from `Algebra.complexToReal`.
