[JSC][Temporal] Implement Intl.DateTimeFormat Temporal support and
toLocaleString
https://bugs.webkit.org/show_bug.cgi?id=315637
rdar://178012405
Reviewed by Yusuke Suzuki.
Implement the Temporal proposal's Intl.DateTimeFormat integration:
HandleDateTimeValue,
SameTemporalType, AdjustDateTimeStyleFormat, GetDateTimeFormat, FormatDateTime,
FormatDateTimeToParts, FormatDateTimeRange, and FormatDateTimeRangeToParts.
Introduce TemporalFieldKind to drive per-type ICU skeleton filtering, lazy
formatter
caching, and timezone selection (GMT for plain types, DTF timezone for Instant).
Calendar validation throws RangeError before TypeError; iso8601 is exempt only
for
PlainDate and PlainDateTime.
Wire up toLocaleString on all six Temporal prototype objects. Remove the
//@ skip directives that were blocking toLocaleString tests. Remove 201
now-passing test262 expectations.
Test: JSTests/stress/intl-datetimeformat-temporal-formatter-cache.js
