[jdk8u-dev] RFR: 7102969: currency.properties supercede not working correctly [v2]

[Severin Gehwolf]

> This is a backport of JDK-7102969 and JDK-8157138 both of which were done as a single patch in JDK 9 (and also included JDK-8149452 which isn't part of this backport because it changes CLDR related things which I think are too risky to backport and only applying those hunks fails the newly added test for it). The reason why I propose to backport this is:
> 
> 1. Oracle backported it to 8u461
> 2. It's a more thorough fix of [JDK-8353433](https://bugs.openjdk.org/browse/JDK-8353433) which got added to avoid a test failure for an ISO 4217 Amendment 176 update. See [JDK-8353579](https://bugs.openjdk.org/browse/JDK-8353579) and [this comment](https://bugs.openjdk.org/browse/JDK-8353433?focusedId=14771442&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14771442) for details.
> 
> I've mostly applied hunks manually and omitted the test for JDK-8149452 and the related `jdk/make/src/classes/build/tools/cldrconverter/CLDRConverter.java` changes.
> 
> Since this also fixes JDK-8353433, the change to the `CurrencyData.properties` has been revered (see separate commit). Backports of JDK-7102969 and JDK-8157138 fix the `java/util/Currency/ValidateISO4217.java` test as well.
> 
> Testing:
> - [x] `jdk/test/java/util/Currency/` tests
> 
> Thoughts? Please review! Thanks in advance.
