pdfium: support for pages when using PDF import with pdfium

Moving PDF to use VectorGraphicData in Graphic has temporary
removed the support for showing different PDF pages when opening
the PDF using pdfium (LO_IMPORT_USE_PDFIUM=1).
This adds the support for back by specifying whcih PDF page to
render when creating the VectorGraphicData (and can't be changd
afterwards), which is used to create a Graphic and contains the
PDF source data array.
