<i18n dev> RFR: 8304982: Emit warning for removal of `COMPAT` provider [v2]

Mon Apr 3 18:11:03 UTC 2023

> This is a precursor to the future removal of the `COMPAT` locale data provider. Before the actual removal of the provider, warn the users who explicitly specify `COMPAT` at the command line in order for their smooth migration to CLDR. A CSR has also been drafted.
