pdfium: fix setting the size of the document when opening PDF
When loading the pages of PDF, the size of the document was set to the wrong value. Size returned by ImportPDFUnloaded was in pixels, which is not really useful considering the svx and sd core uses 100th mm as the unit and converting it to a device dependent pixel will just bring grief. Also we don't need to know the size in pixels until we actually render. This change removes DPI as the parameter to the ImportPDFUnloaded and changes the code to get the size of the page from the PDF as points and converts that to 100th mm.
