Ignore units not in the data type when formatting with Intl

[ptomato]

If the formatting options request a time zone name for any type except
Absolute, or a day for YearMonth, or a year for MonthDay, we want to
ignore that, since the data model for that type doesn't contain those
units.

Closes: #572

Does this need a spec change, too?

Does this need a spec change, too?

I don't think so (https://tc39.es/proposal-temporal/#sec-partitiondatetimepattern), time zone doesn't seem to be requested for any of those types. (Although I'm not so up to date on that part of the spec and it has a big TODO on it anyway.)

[sffc]

OK, yeah, it looks like timeZoneName is not in the Supported Fields table. We should add it as supported for Temporal.Absolute. I filed #591 to follow up on that.

Looks great, thanks.
