LibJS: Include hour-cycle in DateTimeFormat options
This is a normative change to the Intl spec:
20e5c26
Note that this doesn't actually affect us. Its purpose is to provide the
hour-cycle to BestFitFormatMatcher. This AO is implementation defined,
and ours just invokes BasicFormatMatcher, which doesn't use this field.
We could now have LibUnicode generate this field and use it to find a
better format pattern, though.
