For convenience, adds some functions to TemporalHelpers to assert that two
Temporal objects are equal, for Duration, Instant, PlainDateTime,
PlainTime, and ZonedDateTime.

In a previous version of the specification, there was a fallback to the
intrinsic getOffsetNanosecondsFor when it was undefined.
Prior to this patch, the modified test invoked the `arrayContains`
utility function without referencing its return value. Unlike Test262's
assertion functions, `arrayContains` does not throw an error when the
expectation is violated, so the prior usage did not influence test
results.
Additionally, the prior version of this test documented incorrect
expectations regarding the expected value produced by the method under
test. Due to the above, these expectations were not enforced.
Correct the test's expectations and enforce those expectations with a
function that will reliably produce an exception if violated.
