Migrate locale data to icu to remove the overlap in luni

Differences in DateFormat/SimpleDateFormat
1. Icu supports extra pattern chars[1], refert to http://www.icu-project.org/apiref/icu4j/com/ibm/icu/text/SimpleDateFormat.html; most failures in test_applyLocalizedPatternLjava_lang_String() are caused by that.
2. For pattern "ZZZZ", ICU has different output, for example icu returns GMT-07:00 but RI returns -7000.
3. For pattern "z" and "zzzz", ICU has different output, for example icu returns "GMT+14:00, Line Islands Time" for "z, zzzz" but RI returns "LINT, Line Is. Time" in "Pacific/Kiritimati";
most failures in test_timeZoneFormatting() are caused by above 2.
4. test_formatLjava_util_DateLjava_lang_StringBufferLjava_text_FieldPosition() reported as ICU ticket 6089.
5. icu has different explanation on the pattern 'y'. 


To be continued.
