[OpenType] Language System Tags for orthographies using ı U+0131

[moyogo]

Khinalug [ISO 639-3: kjj], Udi [udi] and Talysh [tly] in Azerbaijan use alphabets similar to Azerbaijani.

Like Azerbaijani 'AZE ' [aze], Crimean Tatar 'CRT ' [crh], Gagauz 'GAG ' [gag], Kazakh 'KAZ ' [kaz], Khorasani Turkic 'KMZ ' [kmz], Krymchak 'JCT ' [jct], Tatar 'TAT ' [tat], Turkish 'TRK ' [tur], Zazaki 'ZZA ' [zza] which may need special features in fonts to prevent ı U+0131 LATIN SMALL LETTER DOTLESS I from looking like i U+0069 LATIN SMALL LETTER I in some contexts, for example if a ligature fi is formed.
