Previously, "nested" time zone property bags were unwrapped up to one
level. That is, this object:
{
timeZone: {
// ...Temporal.TimeZone methods
}
}
would not be considered to implement the TimeZone protocol, but would have
its timeZone property used instead, if it were passed to an API that
required a TimeZone protocol object.
These nested property bags are no longer supported. Discussion:

Corresponding normative PR:

This is the replacement of the old API with the new API, .timeZoneId and
.getTimeZone(). Semantics will be corrected in the following commit.
Normative PR: https://github.com/tc39/proposal-temporal/pull/2482
There were two cases where tests in intl402/ had some duplication of tests
that are in built-ins/ as well. Remove this duplication, and restrict the
intl402/ tests to testing things that can't be tested on all hosts.
For cases in the previous commit that actually removed some functionality
from tests in built-ins/, add corresponding tests in intl402/ to preserve
test coverage of that functionality for hosts that do support Intl.
