XFA - Support non-embedded fonts without a Widths entry

- some pdf use some fonts which are not embedded or they don't have any width array or don't have any css info (e.g. for standard fonts or Arial).
  - so add widths arrays for Liberation fonts in order to compute the ones for other fonts in using scale factors array.
