Support print preset options for pdf document

Blink changes to add support for print preset options
for pdf documents. When pdf document has print preset options
set, then print preview mode should use those options.

This patch adds changes required to get print preset options
from plugin. Also, this patch removes getPrintCopiesForPlugin() 
that was added initially and is no longer required.
