XFA - Fix font scale factors (bug 1720888)

Browse source 
- All the scale factors in for the substitution font were wrong because of different glyph positions between Liberation and the other ones:
    - regenerate all the factors
  - Text may have polish chars for example and in this case the glyph widths were wrong:
    - treat substitution font as a composite one
    - add a map glyphIndex to unicode for Liberation in order to generate width array for cid font
