RFR: [11u] 8205432: Replace the placeholder Japanese era name

[Andrew John Hughes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8205432
Webrev: https://cr.openjdk.java.net/~andrew/openjdk8/8205432/webrev.01/

This is a largely clean backport with some minor adjustments, as
mentioned in Christoph's e-mail [0]:

make/data/cldr/common/main/ja.xml -> applied against
src/jdk.localedata/share/classes/sun/util/cldr/resources/common/main/ja.xml
(file has moved)

make/data/cldr/common/main/root.xml -> applied against
src/jdk.localedata/share/classes/sun/util/cldr/resources/common/main/root.xml
(file has moved)

test/jdk/java/time/test/java/time/format/TestNonIsoFormatter.java ->
copyright hunk failed as date is already 2019 from previous era fix

test/jdk/java/util/Calendar/JapaneseLenientEraTest.java -> copyright
hunk failed as date is already 2019 from previous era fix

The remaining changes Christoph mentions are no longer applicable due to
other backports:

* The missing TestScripts tests mentioned in Christoph's e-mail are now
present, thanks to the backport of JDK-8208656 and the patch applies
cleanly to them.

* The missing China test in
test/jdk/java/util/Calendar/JapaneseEraNameTest.java was added by the
backport of JDK-8219890 and the patch applies cleanly after that.
