* Extended to support UTC offset time zones per ECMA-402 PR #788 (ES2026).
|

* The abstract operation validates both:
|
|
* 1. UTC offset identifiers (e.g., "+01:00", "-05:30")
|
|
* 2. Available named time zone identifiers from IANA Time Zone Database
|
|
*

|
* @param tz - The timezone identifier to validate
|
|
* @param implDetails - Implementation details containing timezone data
|
|
* @returns true if timeZone is a valid identifier
