d83d26cc5d ICU-9972 Fix Chinese/Dangi Calendar getActualMaximum(UCAL_DAY_OF_YEAR) 
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.
