[ios] Improve TTS voice selection

Browse source 
This commit allows a user to select more voices (e.g. English (United States),
English (India)). Currently, it's only possible to select a subset of the
available voices on iOS. For example, if a user selects English as TTS
language, an Australian voice is selected because en_AU comes before en_US in
the voice list of iOS.

Fixes #6840
Fixes #3222
Fixes #2178
