TZNames.GetCountryNames() returns territories without time zones and different results per locale

[RobJohnston]

Calling TZNames.GetCountryNames() with the English locale gets data from https://www.unicode.org/repos/cldr/tags/release-34/common/main/en.xml, which includes 4 territories without time zones:

• EZ - Eurozone
• UN - United Nations
• XA - Pseudo-Accents
• XB - Pseudo-Bidi

Calling it with the French locale gets data from https://www.unicode.org/repos/cldr/tags/release-34/common/main/fr.xml, which does not include "XA" nor "XB".

Expected results:

1. different locales return the same number of territories
2. Territories without time zones are not returned

Indeed, this is a side effect of the nature of the source data in CLDR. We'd have to do some further analysis and manipulation of the data to resolve this.

A PR would be welcome.
