LibJS: Implement Intl.NumberFormat V3's [[UseGrouping]] changes
In the main spec, [[UseGrouping]] can be true or false. In V3, it may be one of: auto: Respect the per-locale preference for grouping. always: Ignore per-locale preference for grouping and always insert the grouping separator (note: true is now an alias for always). min2: Ignore per-locale preference for grouping and only insert the grouping separator if the primary group has at least 2 digits. false: Ignore per-locale preference for grouping and never insert the grouping separator.
