Disable multicol when printing.

Until crbug.com/99358 is fixed, we cannot really print multicol properly.

The old multicol implementation has code (in C++) to prevent multicol when
printing, but since the new implementation creates a different layout tree
structure for multicol, it's going to be quite some work to remove multicol
containers when switching the document to printing. So let's do it in CSS
instead.
