The internal printing code can only handle N-up for content from Blink
or the PDF plugin. For any other plugin, which is effectively just
Flash, the N-up setting does not work. So do not show the setting in the
Print Preview UI in this case.

To do this, take advantage of an earlier CL that exposes whether the
content being printed is PDF or not, and plumb that setting into the
Print Preview UI and show the pages-per-sheet control based on that.
