<i18n dev> RFR: 8174269: Remove COMPAT locale data provider from JDK [v5]

Tue Feb 27 00:24:08 UTC 2024

> This PR intends to remove the legacy `COMPAT` locale data from the JDK. The `COMPAT` locale data was introduced for applications' migratory purposes transitioning to `CLDR`. It is becoming a technical debt and now is the time to remove it (we've been emitting a warning at JVM startup since JDK21, if the app is using `COMPAT`). A corresponding CSR has also been drafted.
