Swift: Accept standardized CSV sink labels

[geoffw0]

There's been an effort to standardize the CSV sink labels we use between different languages. This change adds the standardized labels for Swift (but does not remove the old labels - I'm open to discussion on whether and how we should do that, but personally I don't think they're doing a lot of harm).

I think Swift should embrace the fact that we don't have a deprecation period yet and just get rid of the old labels 😃. One way of doing things is better than two in this case, I think!

FYI, for Java I'm removing the old labels and including a change note on the PR. See #12916.

OK, I've removed the old labels. I don't think we have any CSV sink models that use these particular labels, and we're not doing change notes yet, so that should be all that's needed.

Looks like I was wrong (I searched but my terms were a bit too narrow). Fixed now.

LGTM once CI is happy!
