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

Passed tier1 tests, as well as jdk/test/java/util/TimeZone, jdk/test/java/time, jdk/test/sun/util/resources, jdk/test/sun/text/resources, and jdk/test/sun/util/calendar tests locally. Passing GHA sanity tests (other than known failures).

/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 a couple known, unrelated failures)
• Tier 1 tests locally
• jdk/test/java/util/TimeZone, jdk/test/java/time, jdk/test/sun/util/resources, jdk/test/sun/text/resources, and jdk/test/sun/util/calendar tests locally
