8383825: Incorrect handling of Hawaii_Aleutian metazone

[naotoj]

This fixes a regression found while backporting the fix for JDK-8382020.

The previous fix records metazone names only when processing the default (001) time zone for the metazone. However, it did not handle the case where that default time zone also has its own zone-specific names.

This does not show up in mainline for Hawaii_Aleutian metazone, because the metazone's default time zone is America/Adak, which maps back to the Hawaii_Aleutian metazone. In JDK 25, however, the default time zone for Hawaii_Aleutian is Pacific/Honolulu, which has its own zone-specific names so that Hawaii can use short names such as HST/HDT instead of HAST/HADT.

As a result, when the JDK-8382020 fix is backported to JDK 25, the Hawaii_Aleutian metazone names are not generated during the build. This change processes metazone names before zone-specific names, so the default-zone metazone entry is still recorded even when the default zone has its own names.
