pdfium: Make Insert -> Image... use VectorGraphicData for PDF.

In principle, the current Svg/Emf/Wmf and PDF handling is trying to
achieve the same thing: Keep the original stream untouched, provide a
replacement graphics, and a kind of rendering.

To hold the data, the Svg/Emf/Wmf and PDF were using different structures
though.  This commit consolidatates that, and makes the Insert
-> Image... (for PDF) actually using the VectorGraphicData to hold the
original stream.

This breaks loading the PDF as a document via PDFium - I'll fix it in
the next commit(s).
