These test cases ensure that DST disambiguation does not take place on
intermediate values that are not the start or the end of the calculation.
Note that NormalizedTimeDurationToDays is no longer called inside
Temporal.Duration.prototype.add/subtract, so a few tests can be deleted.
Other tests need to be adjusted because NormalizedTimeDurationToDays is
no longer called inside Temporal.ZonedDateTime.prototype.since/until via
DifferenceZonedDateTime, although it is still called as part of rounding.
In addition, new tests for the now-fixed edge case are added, and for the
day corrections that can happen to intermediates.

Based on PR #3807 which had generated these tests from templates,
but was stuck due to issue #3808.

Add tests to ensure that:
1. First `byteLength` isn't larger than `maxByteLength`.
2. Then `OrdinaryCreateFromConstructor` is called.
3. And finally `Create{Shared}ByteDataBlock` is called.
This adds tests specifically for every kind of case that changes due to
the tweak to the date difference algorithm: differences from a longer
month to a shorter month, when the months are adjacent, in the same year
but not adjacent, and in different years.
Also adds tests for a case that does *not* change, but would trip on an
incorrectly implemented algorithm: when the intermediate months value
falls at the end of February.
There was incidental coverage of the change to the date difference
algorithm in other tests. Those are adjusted, as well.
Normative change: https://github.com/tc39/proposal-temporal/pull/2759
Consensus in February 2024
Adapts the tests that checked arbitrarily long loops, to now check that an
exception is thrown if the loop would happen.
Adds tests that exercise the newly added checks on return values of
getPossibleInstantsFor and getOffsetNanosecondsFor that limit UTC offset
shifts to 24 hours or less.
Also updates some step numbers in related tests.
The existing tests didn't cover some edge cases where implementations
have to compute the exact result of `numerator / denominator`, where at
least one of `numerator` and `denominator` can't be exactly represented
by an IEEE-754 double precision floating point value.
"precision-exact-mathematical-values-5.js" gets added in #3961, so the
new tests from this commit start at "precision-exact-mathematical-values-6.js".
NormalizedTimeDurationToDays can no longer loop indefinitely, because at
a certain point we will hit the upper bound of MAX_SAFE_INTEGER, so rename
the test to reflect that it can loop an arbitrary but limited number of
times.
Add a test for the RangeError condition in NormalizedTimeDurationToDays
when the time zone calculates a day length that is not a safe integer
number of nanoseconds.
While editing these tests, rename them to match the current name of the AO
and make sure the step numbers are up to date. (Normally I wouldn't care
so much about that, but these tests can be pretty confusing so it's good
to be able to refer to the spec text.)
Adapts or removes tests that relied on creating durations that are now out
of range. Adds new tests for maximum in-range and minimum out-of-range
durations.

A few results change because the algorithm previously used for rounding
didn't always add duration units to dates in RFC 5545 order, and we also
introduce a special case for rounding with largestUnit years or months and
smallestUnit weeks.
