XFA - Get line height from the font

- when the CSS line-height property is set to 'normal' then the value depends of the user agent. So use a line height based on the font itself and if for any reasons this value is not available use 1.2 as default.
  - it's a partial fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1717681.
