Also fix ICU-12620 which is mark duplicate of ICU-9972 just now. and fix ICU-22258. Separate the new year and winter solstice cache since the calculated value for these two calendar are mostly but not always the same due to slightly different observation timeZone. Remove the epochYear and zoneAstroCalc from the member data and instead return them from a getStting() method with the two caches since all four of them are constant per subclass of ChineseCalendar and do not need to be different per object. The known issues in the TestLimit is caused by both Calendar get/put the value from the same cache while the calculated result depends on the timeZone zoneAstroCalc.
