vcl: When exporing PDF, write the correct page of embedded PDF

We can display PDF as an graphic in the document, where the PDF
is treated as a vector graphic and rendered with Pdfium. When
in that case we export the document as PDF, we can insert the
original PDF page as an reference XObject. This workes fine,
however the PDF as an graphic also contains the page number,
which page should be rendered. This was not taken into account
in the PDF export - it was hardcored to first page.

This extends the support so it reads the page index from the
graphic, and sets the correct PDF page.
