Arabic ligitures

 From github. https://github.com/golang/go/issues/12298

Arabic ligitures have been deprecated[1], despite a need for both ligitures
and non-ligature versions of the same glyphs. Amiri uses contextual
alternatives for الله.  These ligatures are used in religious documents[2]
via pictures, which seems to be what the current Unicode standard recommends.
Unlike the presentation forms, there is case for these phrases and formulas
to be available both in ligature and non-ligature form.

These ligatures should be non-deprecated and subject to canonical
decomposition, rather than compatibility decomposition.
