Expose pdfium functionality for N-up mojo service.

Added two new functions to expose pdfium functionality to the
to-be-created N-up conversion mojo service.

ConvertPdfPagesToNupPdf will take multiple PDF pages and import them
into a N-up PDF.

ConvertPdfDocumentToNupPdf will take an entire PDF document and convert
it to a N-up PDF document.

In printing, 2-up, 3-up, or more generally N-up refers to a page
layout strategy in which multiple pages are composited onto a
single page.
