Every official language, in JSON: 113 listed, five shipped so far

The language list comes from CLDR (official in a UN member state, plus the
six UN languages), with autonyms and text direction supplied for the 21
that ICU does not know. Strings move from resx to one JSON file per
language, looked up by code, so a language unknown to ICU or MSBuild still
loads; tools/strings.cs checks keys and placeholders in CI. Arabic, Hindi
and Chinese drafts prove right-to-left and system-font fallback.
