[JSC] Use `std::unique_ptr` for ICU resources in Intl to fix `UEnumeration`
leak
https://bugs.webkit.org/show_bug.cgi?id=308919
Reviewed by Yusuke Suzuki.
availableNamedTimeZoneIdentifier() leaks a UEnumeration on every call
with a valid timezone name, because the early return on match skips
uenum_close(). Measured leak is ~210 bytes per Intl.DateTimeFormat
creation with a named timeZone.
Also convert the other raw ICU pointers in these files to
std::unique_ptr with ICUDeleter for consistency. They were not leaking,
but the same file already uses std::unique_ptr for the same ICU APIs
elsewhere.
