sw: copy bookmarks in SwDoc::CopyPageDescHeaderFooterImpl()

When importing tdf113521-1.doc, a footer is copied, but the fieldmark in
it is not copied, so there are CH_TXT_ATR_FIELD* in the copy without
matching fieldmark, and the result is
sw/source/filter/ww8/wrtw8nds.cxx:2342: virtual void MSWordExportBase::OutputTextNode(SwTextNode&): Assertion `pFieldmark' failed.
