[JSC][Temporal] Guard PlainDate construction against out-of-range years;
consolidate CalendarResolveFields
https://bugs.webkit.org/show_bug.cgi?id=320927
rdar://183960408
Reviewed by Yusuke Suzuki.
PlainDate's constructor now sanitizes `year` itself instead of asserting and
trusting every caller to check first — this was crashing on debug builds
(e.g. indianSakaToISO, huge duration arithmetic) and silently wrapping
values incorrectly in a couple of places. Added an int64_t overload and a
sentinel() factory for callers whose month/day may be equally untrustworthy.
Also fixed PlainYearMonth.prototype.toPlainDate misusing the year sentinel
as a day poison value (wrong clamp direction under overflow:constrain), and
a possible UB static_cast in the PlainMonthDay constructor.
Consolidated CalendarResolveFields/CalendarDateToISO into single
implementations in CalendarFields.cpp, removing a second undocumented
duplicate in TemporalCalendar.cpp and monthDayFromFields's own internal
duplication.
