Language handler: add ISO 639 codes in order to reduce confusion for …

…users. Re nvaccess#7284.

Reviewed by Mick Curran (NV Access) and others: suppose a user changes to another language by accident, a language he or she cannot understand, especially changes the Windows display language by accident. So how can they return to a language they know? This cannot be done with absence of ISO 639 language codes.
