[JSC][Temporal] Fix Ethiopic AA era mapping
https://bugs.webkit.org/show_bug.cgi?id=319787
Reviewed by Yijia Huang.
ICU represents the historical Ethiopic AA era as era 0 and the modern AM era as
era 1. Map those values explicitly in both directions so Temporal accepts AA
property bags and reports the correct era for historical dates.
Test: JSTests/stress/temporal-calendar-icu-bridge-non-iso.js
* JSTests/stress/temporal-calendar-icu-bridge-non-iso.js:
- Add modern AM and historical AA parsing and field-output coverage.
* Source/JavaScriptCore/runtime/temporal/core/CalendarICUBridge.cpp:
(JSC::Temporal::mapICUEraToTemporalEra):
(JSC::Temporal::mapTemporalEraToICUEra):
- Distinguish Ethiopic AA and AM ICU era values.
