Frank Tang fe1245edf8 [Temporal] Fix ZDT hoursInDay for non-integer hours 
The hoursInDay could be fractional number on the date of changng
daylight saving time for time zone in half hours or some historical time
zone.
Ex: Australia/Lord_Howe on Sunday, April 3, 2022, 2:00:00 am clocks were
turned backward 0:30 hours to Sunday, April 3, 2022, 1:30:00 am local
standard time instead. so that day will have 24.5 hours.
On Sunday, October 2, 2022, 2:00:00 am clocks are turned forward 0:30
hours to Sunday, October 2, 2022, 2:30:00 am local daylight time
instead. So the hoursInDay for that day is only 23.5 hours.

Historically, Singapore from 1933 to 1941 moved clocks forward 20 minutes for daylight savings, resulting the day in 24.33333 and
23.66667 hours.

Test covered in https://github.com/tc39/test262/blob/main/test/staging/Temporal/ZonedDateTime/old/dst-properties.js

Change the return type from MaybeHandle<Smi> to MaybeHandle<Object> so
we can return non integer value. Also change the method of division by
first convert the value to second in BigInt, then divid 3600 (number of
seconds in a hour) in double.

README 

This directory contains code for binding the test262 test suite
into the v8 test harness. The tests are checked out as a dependency from

  https://chromium.googlesource.com/external/github.com/tc39/test262

at a revision specified in the DEPS file as 'data' in this directory. They are
fetched with 'gclient sync'. To update to a newer version, please change the
DEPS file.

Using a newer version, e.g. 'deadbeef' may be possible but the tests are only
known to pass (and indeed run) with the DEPS revision. Example:

  cd data
  git fetch
  git checkout deadbeef

If you do update to a newer revision you may have to change the test
harness adapter code since it uses internal functionality from the
harness that comes bundled with the tests.  You will most likely also
have to update the test expectation file.
