LibLocale+LibJS: Update to CLDR version 42.0.0

There were some notable changes to the CLDR JSON format and data in this
release.

The patterns for a date at a specific time, i.e. "{date} at {time}", now
appear under the "atTime" attribute of the "dateTimeFormats" object.

Locale specific changes that affected test-js:

All locales:

* In many patterns, the code points U+00A0 (NO-BREAK SPACE) and U+202F
  (NARROW NO-BREAK SPACE) are now used in place of an ASCII space. For
  example, before the "dayPeriod" fields AM and PM.

* Separators such as U+2013 (EN DASH) are now surrounded by U+2009 (THIN
  SPACE) in place of an ASCII space character.

Locale "en":

* Narrow localizations of time formats are even more narrow. For
  example, the abbreviation "wk." for "week" is now just "wk".

Locale "ar":

* The code point U+060C (ARABIC COMMA) is now used in place of an ASCII
  comma.

* The code point U+200F (RIGHT-TO-LEFT MARK) now appears at the
  beginning of many localizations.

* When the "latn" numbering system is used for currency formatting, the
  currency symbol more consistently is placed at the end of the pattern.

Locale "he":

* The "many" plural rules category has been removed.

Locales "zh" and "es-419":

* Several display-name localizations were changed.
