[JSC] Add missing `U_FAILURE(status)` for `actualLunisolarMonthLength`
https://bugs.webkit.org/show_bug.cgi?id=320313
Reviewed by Yusuke Suzuki.
The U_FAILURE(status) check sat after the early return for non-Chinese/Dangi
calendars (i.e. Hebrew), so it never guarded the ucal_getLimit call: on ICU
failure the function returned an engaged optional { 0 } and the callers
clamped the day to 0 under overflow: "constrain" instead of throwing a
RangeError. Check the status right after ucal_getLimit.
