Khaled Hosny c3f590bb1e [arabic] Support legacy PUA shaping
Support legacy pre-OpenType Windows 3.1-era fonts, by remapping PUA code
points in cmap table and letting our fallback shaper build the GSUB
table.

Uniscribe applies also mset-like substitution, but our fallback mark
positioning gives better results, so this is not implemented.
