pdfium: only init pdfium library one and destroy on LO exit
With more and more usage of PDFium, it is hard to keep track of
the life-time of the PDFium library, so it can happen that a
FPDF_DestroyLibrary happens when we still have another instance
where PDFium is still use. The result of this is a crash. To
prevent this, just initialize the library once and delete, when
on LO exit.
This can be improved in the future to only keep the library
active when in actual use.
