<i18n dev> RFR: 8340477: Remove JDK1.1 compatible behavior for "EST", "MST", and "HST" time zones

[Naoto Sato]

Removing the old compatibility behavior switch for JDK1.1. With the integration of tzdata2024b, definitions of those three (deprecated) IDs changed again, so maintaining the JDK11 compatibility got less useful. Removing the compatibility behavior makes the code and test simpler. A CSR for the behavior change is drafted too.
