[8u] RFR: JDK-8275766: (tz) Update Timezone Data to 2021e

[Dmitry Cherepanov]

JBS: https://bugs.openjdk.java.net/browse/JDK-8275766
Webrev: https://cr.openjdk.java.net/~dcherepanov/openjdk8u/8275766/webrev.01

Please review the update to tzdata2021e
  * updated manually from the rearguard version (tzdata2021e-rearguard.tar.gz generated by `cd tzdb-2021e && make rearguard_tarballs`)
  * the diff for ZoneInfoFile.java applied cleanly
  * updated the copy of the timezone data in the test folder

Will submit a separate request for https://bugs.openjdk.java.net/browse/JDK-8276536

Testing: tests for sun.util.calendar and java.time.test passed

Thanks

Dmitry
