[JSC] `Intl.DurationFormat` drops zero minutes and seconds after a numeric
unit
https://bugs.webkit.org/show_bug.cgi?id=324561
Reviewed by Yusuke Suzuki.
new Intl.DurationFormat("en", { hours: "numeric" }).format({ hours: 1 }) returns
"1" instead of "1:00:00", and resolvedOptions() reports minutesDisplay and
secondsDisplay as "auto". The equivalent { style: "digital" } already returns
"1:00:00".
When a unit's style is unspecified and the previous unit is numeric or 2-digit,
GetDurationUnitOptions [1] defaults the display to "auto" only for units other
than minutes and seconds. intlDurationUnitOptions set "auto" for every unit in
that case. Follow the spec.
