Verify valid language option values (various)

10. If options is undefined, then
11. Else
a. Let options be ? ToObject(options).
12. Set tag to ? ApplyOptionsToTag(tag, options).
ApplyOptionsToTag( tag, options )
...
2. If IsStructurallyValidLanguageTag(tag) is false, throw a RangeError exception.
3. Let language be ? GetOption(options, "language", "string", undefined, undefined).
4. If language is not undefined, then
a. If language does not match the unicode_language_subtag production, throw a RangeError exception.
IsStructurallyValidLanguageTag ( locale )
The IsStructurallyValidLanguageTag abstract operation verifies that the
locale argument (which must be a String value)
represents a well-formed Unicode BCP 47 Locale Identifier" as specified in
Unicode Technical Standard 35 section 3.2, or successor,
features: [Intl.Locale]
