Bug: https://bugs.openjdk.java.net/browse/JDK-8254177
Webrev: https://cr.openjdk.java.net/~andrew/openjdk8/8254177/webrev.01/

This is largely a rewrite rather than a backport. 8u still uses the
old rearguard tzdata format, so they were generated from the
tzdata2020b release and then copied over the ones in the jdk
repository (both in make/data/tzdata and

The same modifications are made as in the patch for later JDK
versions, with pacificnew and systemv being removed, and references
to them and the US/Pacific-New zone being removed from the
makefiles and translations resources.

The sorting addition in test/sun/util/calendar/zi/TestZoneInfo310.java
is retained from the 11u version. The other test changes don't
exist in 8u.

Ok for 8u?
