Experimental API for N-up feature support for print
FPDF_ImportNPagesToOne function is added to support N-up feature
for print.
If numPagesOnXAxis * numPagesOnYAxis == 0
Returns a nullptr.
If numPagesOnXAxis * numPagesOnYAxis == 1
Creates a new PDF document, and import one page to each output
page of the PDF document
If numPagesOnXAxis * numPagesOnYAxis > 1,
FPDF_ImportNPagesToOne imports multiple pages onto the same page.
This feature is intended for print pipeline to use.
