sc export chart as graphic: handle PDF

The context menu for Calc charts would call into
GraphicFilter::ExportGraphic(), which has explicit code for e.g. SVG,
but not for PDF. The graphic exporter to PDF is only meant to work with
images backed with PDF data, not with all shapes.

Fix the problem by explicitly handling PDF in
GraphicHelper::SaveShapeAsGraphic() in svx/, and invoking the normal PDF
export in that case. Continue to fall back to XGraphicExportFilter for
other formats.

This requires passing down the current document from sc/.
