Treat `column-count: 1` as `column-count: auto` in Apple Books

Reviewed by Alan Baradlay.
There are some iBooks that set `column-count: 1` where they probably
should use `column-count: auto`, and this is creating nested multicol
situations that are not printing properly (because we don't fragment
multicol correctly). This change treats `1` the same as `auto` in
Apple Books until we're able to fix the underlying problem.
This is a follow-up to https://commits.webkit.org/300787@main
