Make empty document always have empty privileges

This landed earlier as part of a larger change that got reverted for
unrelated reasons. Now re-land it by itself. See
  https://pdfium-review.googlesource.com/c/pdfium/+/33370

If we don't have a document, then we can't dynamically tell if it is
an XFA doc, so there's no reason to believe it should have all permissions.
If there is an XFA doc under the covers, then the extension will give
us the value.
