Sorry, I don't know what a TznGeoRefTe is; that notion is not part of 
tzdata.  I expect the notion comes from some downstream use of tzdata, 
and perhaps you could ask whoever is in charge of that downstream 
version what happened to Aruba in their downstream copy.

In tzdata America/Aruba is still there, and is an alias for 
America/Curacao.  This alias was created in tzdata release 2013e dated 
2013-09-19 23:50:04 -0700.  Formerly America/Aruba was a separate zone, 
but its data were unreliable and out of scope for tzdata so it was 
turned into a link.  Notification for the change is in the NEWS file 
distributed as part of tzdata.

> Are all countries identified in IANA with a Time Zone Name (TznGeoRefTe)?

No, not every country with a two-letter country code has a time zone 
identifier.  For example, Bouvet Island (country code BV) has no time 
zone identifier, as it's uninhabited.  Although we formerly tried to 
give every country an identifier, counterexamples like Bouvet and 
political disputes about what constitutes a "country" have put something 
of a damper on that idea, and the topic is controversial.
