Data loading component for new time zone picker.

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. Test: SettingsRoboTests Bug: 62255208 Change-Id: I244c391a41b0b53cd3f7857f9c0d1ef766a39b17
