share spPaperSizeTable ( and associated access code ) in msfilter

PageSetup.PaperSize implementation more or less copy&pasted the
papersize conversion code from oox, this is a followup to remove
the duplication. ( Probably the binary filter could be converted
to use this also saving yet another nearly similar implementation )
