RFR: 8321480: ISO 4217 Amendment 176 Update [v3]

[Justin Lu]

> Please review this PR which incorporates the ISO 4217 Amendment 176 Update. As the replacement of `ANG` to `XCG` won't occur until 2025, this change does not need to go into JDK22. `HR` was also updated to remove the past cutover dates.
> 
> An existing test in _ValidateISO4217.java_ checked that `Currency::getAvailableCurrencies` had all the expected currencies. This method returns all currencies, including ones to take place in the future (e.g. `XCG`). The expected currencies `Set` the method was test against had to be updated to also include future currencies as well.
> 
> Additionally, this change also converted a parameterized test to a normal JUnit test, due to output overflow.
