The resolved locale doesn't include a hc Unicode extension value if the
hour12 or hourCycle option is also present.

11.1.2 CreateDateTimeFormat( dateTimeFormat, locales, options, required, defaults )
...
13. Let hour12 be ? GetOption(options, "hour12", boolean, empty, undefined).
14. Let hourCycle be ? GetOption(options, "hourCycle", string, « "h11", "h12", "h23", "h24" », undefined).
15. If hour12 is not undefined, then
a. Set hourCycle to null.

9.2.6 ResolveLocale(availableLocales, requestedLocales, options, relevantExtensionKeys, localeData)
...
8. For each element key of relevantExtensionKeys in List order, do
...
i. If options has a field [[<key>]], then
i. Let optionsValue be options.[[<key>]].
ii. Assert: Type(optionsValue) is either String, Undefined, or Null.
iii. If keyLocaleData contains optionsValue, then
1. If SameValue(optionsValue, value) is false, then
a. Let value be optionsValue.
b. Let supportedExtensionAddition be "".
