Initial containing block for print not affected by page zoom.

The page zoom factor is not applied to the ICB for printing, yet the
ICB basis for media queries and viewport units were. Use 1 as a page
zoom factor in viewportSizeForViewportUnits and use that method to get
the size for the ICB for evaluating media queries.
