[JSC] Fix Compatibility Issues with `timezone` in `Intl.DateTimeFormat`
https://bugs.webkit.org/show_bug.cgi?id=295856
Reviewed by Darin Adler.
The Intl.DateTimeFormat constructor [1] did not align with the current TC39
specification
regarding the handling of the timeZone option.
This patch implements GetAvailableNamedTimeZoneIdentifier [2] to bring the
behavior
in line with the latest TC39 spec.
