regions: Revise "kz" region config and move it to confirmed list.

- Kazakhstan "kz" region should have three input methods by default
for new user accounts when they enter user session after OOBE flow:
Kazakh (Cyrillic), Russian, US English.

- We only need to list two time zones as the rest are just aliases
of those two, from 2004 onwards.

- testdata/time_zones.yaml sync'd with https://crrev.com/c/2241330
using ./update_testdata.py.
