Temporal: Add tests for IANA legacy name time zones 

Aside from the ones that were already tested in etc-timezones.js, this
adds a test for other IANA legacy names.

Previously these were supported in the TimeZone constructor, but not in
from().

See https://github.com/tc39/proposal-temporal/pull/2292 which is a
normative change that achieved consensus at the July 2022 TC39 meeting.
