Clean up JS Temporal getNamedTimeZoneEpochNanoseconds
https://bugs.webkit.org/show_bug.cgi?id=319296
rdar://182132863
Reviewed by Yijia Huang and Yusuke Suzuki.
getNamedTimeZoneEpochNanoseconds makes a number of ICU calls which could
be reduced by invoking ICU function ucal_getTimeZoneOffsetFromLocal to
deal with time zone offsets. New JSTests/ microbenchmark appears
performance neutral.
