Subject: [PATCH] Fix unreachable code under --harmony-intl-number-format-v3

ICU 71 added new enum value UNUM_APPROXIMATELY_SIGN_FIELD
need to map to "approximatelySign"

We also discover a spec bug in
https://github.com/tc39/proposal-intl-numberformat-v3/issues/99

All the parts of formatRangeToParts should have a source "shared" for
the case that start and end are the same or very close.
