test: move localizationd data from `test-icu-env` to external file

/*
 * This script updates the `test/fixtures/icu/localizationData.json` data
 * used by `test/parallel/test-icu-env.js` test.
 * Run this script after an ICU update if locale-specific output changes are
 * causing the test to fail.
 * Typically, only a few strings change with each ICU update. If this script
 * suddenly generates identical values for all locales, it indicates a bug.
 * Note that Node.js must be built with either `--with-intl=full-icu` after
 * updating ICU, or with `--with-intl=system-icu` if system version matches.
 * Wrong version or small-icu might produce wrong values.
 * Manually editing the json file is fine, too.
