  Call Intl.getCanonicalLocales function with grandfathered language tags.
info: |
  8.2.1 Intl.getCanonicalLocales (locales)
    1. Let ll be ? CanonicalizeLocaleList(locales).
    2. Return CreateArrayFromList(ll).

  9.2.1 CanonicalizeLocaleList (locales)
    ...
    7. Repeat, while k < len
      ...
      c. If kPresent is true, then
        ...
        v. Let canonicalizedTag be CanonicalizeLanguageTag(tag).
      ...

  6.2.3 CanonicalizeLanguageTag ( locale )
    The CanonicalizeLanguageTag abstract operation returns the canonical and case-regularized form
    of the locale argument (which must be a String value that is a structurally valid Unicode
    BCP 47 Locale Identifier as verified by the IsStructurallyValidLanguageTag abstract operation).
    A conforming implementation shall take the steps specified in the “BCP 47 Language Tag to
    Unicode BCP 47 Locale Identifier” algorithm, from Unicode Technical Standard #35 LDML
    § 3.3.1 BCP 47 Language Tag Conversion.
