[JSC] `fractionalDigits` of `Intl.DurationFormat` should be treated as at
most 9 digits if it is omitted
https://bugs.webkit.org/show_bug.cgi?id=274974
Reviewed by Yusuke Suzuki.
According to the spec[1], if the `fractionalDigits` option of
`Intl.DurationFormat` is omitted, it
should be treated as at most 9 digits. However, in the current JSC, it is
treated as exact 0 digits.
The README of the proposal repository[2] states the following:
> If this option is omitted, only nonzero decimals will be displayed and
> trailing zeroes will be omitted.
This patch changes to treat it as at most 9 digits, using the ICU's Fraction
Precision notation[3].
