<i18n dev> RFR: 8342550: Log warning for using JDK1.1 compatible time zone IDs for future removal

[Naoto Sato]

The use of [three-letter time zone IDs](https://download.java.net/java/early_access/jdk24/docs/api/java.base/java/util/TimeZone.html#three-letter-time-zone-ids-heading) has long been deprecated. For their actual removal in the future, making the runtime emit warnings for using those IDs would be desirable.
