sw_redlinehide_4b: visibility checks for EnhancedPDFExport links

SwEnhancedPDFExportHelper should not create links to things that are
hidden by the layout:

* SwCursorShell::GotoFormatField() skips deleted fields
  (this triggers an assert in GetCharRect() with ooo69593-1.odt)

* SwEditShell::GetINetAttrs() skips deleted INet attributes
  (which, as an additional bonus, hides then in the Navigator too)

* SwDoc::GotoOutline() skips outline nodes where we know they have
  been deleted (as seen in ooo66088-9.odt)

* SwFlyFrameFormats are skipped by EnhancedPDFExportHelper itself

* footnotes dito
