XFA - Match font family correctly

- partial fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1716980;
  - some pdf can contain an invalid font family (e.g. 'Windings 3') so in this case remove the space;
  - the font family in typeface attribute doesn't always match the one defined in the FontDescriptor dictionary.
