8352716: (tz) Update Timezone Data to 2025b

[satyenme]

Backport of tzdata2025b. Nearly clean, but contains zone.tab file, which was removed by JDK-8166983.

Reverted change to test/jdk/java/util/TimeZone/TimeZoneData/aliases.txt and .../displaynames.txt when running make in test/jdk/java/util/TimeZone/tools/share to avoid the java/util/TimeZone/Bug6329116.java test failing, just as was done previously for 2024b.

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 (other than known failure).

⚠️ @satyenme This change is now ready for you to apply for maintainer approval. This can be done directly in each associated issue or by using the /approval command.

/approval request for backport of 2025b tzdata. Nearly clean, but needed to re-add zone.tab file, which was removed by JDK-8166983.

Risk: Medium to Low. Tier 1 and relevant tz tests passing, as well as GHA sanity check tests. Backporting tzdata changes is a common enough procedure that, after review, we can be reasonably confident will work as intended.

Testing:

• GHA Sanity Checks (with 1 known, unrelated failure)
• Tier 1 tests locally
• make run-test TEST="jdk/java/util/TimeZone jdk/java/time/test jdk/sun/util/resources jdk/sun/text/resources jdk/sun/util/calendar"
