I wrote a similar test for Temporal.ZonedDateTime.p.toLocaleString, so
while this was fresh I decided to do the same for the other toLocaleString
calendar mismatch tests that were in staging.
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:
https://github.com/tc39/proposal-temporal/pull/2485
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
In https://github.com/tc39/proposal-temporal/pull/2474, which achieved
consensus at the TC39 plenary meeting of 2023-01-31, the implementation-
defined steps for Temporal.Calendar.prototype.mergeFields had their
language tightened, to better specify what implementations must do.
This adds tests covering the new spec language, and moves one related test
out of staging.
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.
Move part of the test of toLocaleString which depends on
15 Amendments to the ECMAScript® 2021 Internationalization API Specification
to intl402. Keep behavior specified in earlier chapters in built-ins
Unfortunately, in #3304 I made a last-minute mistake when I added the
uncallable value to the assertion message, and neglected to test it;
Symbols can't be converted to strings like that, so these tests would
fail. This fixes the assertion messages.

In a previous version of the specification, there was a fallback to the
intrinsic getOffsetNanosecondsFor when it was undefined.
