[Intl] Optimize Intl.PluralRules Previously, Intl.PluralRules was mostly implemented in JavaScript. This patch moves most of the constructor and parts of other methods to C++. The size of the Intl.PluralRules object is reduced by not storing MinimumIntegerDigits, MinimumFractionDigits, MaximumFractionDigits, MinimumSignificantDigits, MaximumSignificantDigits. Instead these are looked up from icu::DecimalFormat as required. Another optimziation is that we don't create the result of resolvedOptions when the Intl.PluralRules object is constructed, but instead defer until this method is called. In the future, we may want to cache the result. This patch also cleans up several error handling paths that shouldn't happen with ICU and instead just crashes should it ever happen.
