In https://github.com/tc39/proposal-temporal/pull/2522 which reached
consensus at the March 2023 TC39 meeting, the functionality of
Temporal.ZonedDateTime.p.toLocaleString was changed substantially, to not
directly pass the ZonedDateTime to any Intl.DateTimeFormat methods. This
adds rewrites of all existing tests for toLocaleString, as well as a few
tests to verify that Intl.DateTimeFormat methods no longer support
Temporal.ZonedDateTime arguments.
As we are rewriting the tests anyway, this also ports all of the
Temporal.ZonedDateTime.p.toLocaleString tests that were in staging, to the
correct format for the main tree.
Following up on #3751 and #3762, this commit makes a few tests
work on both CLDR 42 and CLDR 41. Previously these tests were
tied to a specific CLDR 42 format.

In a previous version of the specification, there was a fallback to the
intrinsic getOffsetNanosecondsFor when it was undefined.
A number of tests for ECMA402 asserted the exact contents of the array
returned by various `resolvedOptions` methods. This conflicted with the
expectation that more options will be introduced by future editions of
the specification.
Update these tests to assert property order more generically in order to
accommodate implementation of future language proposals and more closely
align with similar tests.
Update all `resolvedOptions` tests to produce more meaningful error
messages (including replacing the generic `arrayContains` assertion with
a specific assertion regarding the value of the first array element).
In each case, it's the scalar value associated with the "description" key.
Normally in test262, this is written in either:
- block notation (indicated by '>' or '|'), or
- flow notation, single-line, on the same line as the key.
In the cases addressed by this PR, the value is instead written in:
- (1x) flow notation, *multi*-line, or
- (2x) flow notation, single-line, on the line *after* the key.
These are valid YAML, but they're styles that test262 doesn't otherwise use,
so could conceivably confuse people or harnesses.
This PR changes them to block notation.
Add tests to make sure DateTimeFormat does not call the instanceof
operator and calls OrdinaryHasInstance instead.

intl402/DateTimeFormat/prototype/formatRangeToParts/date-same-returns-single-date.js is using `formatRange` and `format`.
Fix this test to use `formatRangeToParts` and `formatToParts` since it is the intention of this test.
This patch adds additional tests to intl402/DateTimeFormat/prototype/formatRangeToParts/date-same-returns-single-date.js and
intl402/DateTimeFormat/prototype/formatRange/date-same-returns-single-date.js. The new test uses two dates that are practially-equal,
and ensures the implementation uses `format` or `formatToParts` by detecting they are practically-equal.
macOS system ICU is shipping new CLDR, but it has many overrides on the top of it to make the formatted output suitable for the system.
And in timedatestyle-en.js tests, we intentionally override the CLDR data with the different format.
This change modifies the test to accept that alternative output.

The spec draft throws TypeError instead of RangeError.
1.4.5 Intl.DateTimeFormat.prototype.formatRange ( startDate , endDate )
...
4. If startDate is undefined or endDate is undefined, throw a TypeError exception.
1.4.6 Intl.DateTimeFormat.prototype.formatRangeToParts ( startDate , endDate )
...
4. If startDate is undefined or endDate is undefined, throw a TypeError exception.
