When entering the new time zone picker with a fixed offset time zone
(such as UTC) selected, it would crash with a NullPointerException.
This fixes the crash.

This implements a new manual time zone picker that allows selection of a
time zone for a selected country. It also allows selecting a fixed
offset time zone (most importantly Etc/UTC, which is a frequently
requested feature).
The new time zone picker is currently behind a feature flag
(settings_zone_picker_v2), which is disabled by default.

Add new data loading classes for improved manual time zone picker.
These classes use existing sources mostly from ICU4J to construct the
list of regions and timezones to present to the user.
