[jdk21u-dev] RFR: 8356096: ISO 4217 Amendment 179 Update

[Goetz Lindenmaier]

I backport this for parity with 21.0.8-oracle

Resolved adding the bugid in ValidateISO4217.java
There were several test improvements.  They can not be backported
easily. They heavily use modern Java that does not compile with 21.
