[jdk21u-dev] RFR: 8352716: (tz) Update Timezone Data to 2025b

[Satyen Subramaniam]

Backport of tzdata2025b. Nearly clean, but contains `zone.tab` file, which was removed by [JDK-8166983](https://bugs.openjdk.org/browse/JDK-8166983).

Reverted change to `test/jdk/java/util/TimeZone/TimeZoneData/aliases.txt` and `.../displaynames.txt` when adding tzdata to avoid the `java/util/TimeZone/Bug6329116.java` (unmodified) test failing as was done previously for [2024b](https://github.com/openjdk/jdk21u-dev/pull/1143).

Passed tier1 tests and `make run-test TEST="jdk/java/util/TimeZone jdk/java/time/test jdk/sun/util/resources jdk/sun/text/resources jdk/sun/util/calendar"` locally, GHA sanity tests.
