Add 8 more scripts to the font fallback chain.

Fonts for Cham, Coptic, Glagolitic, Kayah Li, Tai Le, Tai Tham, Tai
Viet, and Tifinagh scripts are added to the fallback chain.

This would enable or improve display of texts in Berber languages,
Cham, Church Slavonic, Coptic, Kayah languages, Khün, Northern Thai,
Tai Dam, Tai Dón, Tai Lü, Tai Nüa, and Thai Song.
