Fix some ICU locale data

1. region name for '419' : drop 'Carribean' and make it just 'Latin America'.
   : this cuts down the width of our language selection menu.
     The CLDR upstream plans to make this change as well.
2. Delete the display names for all the numeric region codes other than 419 because
   we don't use them at the moment. This saves about 50kB.
3. Swap the thousand separator and decimal mark symbol in Serbian
4. Fix some date formats in various locales.
5. Merge the upstream (CLDR) changes on the way line-breaking works with
   small kana characters.
6. Update timezone (metazone) display names in ko, it, de, ja (for CrOS and JS I18N API).

BUG=None
TEST=No change in behavior until this change and a follow-up change to update
pre-built binary data files is rolled in to Chrome.
