To be clear, this is mostly about testing tzdata compilers, not consumers of the compiled files (though it would also be useful for that). I think that this would come with a change to `zic` to add either a --test or a --no-test flag which would compile or not compile the test zones as appropriate.

I'm a consumer, and would love to have a "Test" area with stable, define edge cases in the default database so we could use these in our automated testing, rather than picking ones like Pacific/Tongatapu and Pacific/Kwajalein. But, we already filter the list so normal user's don't see Etc and similar, but power users can still use them if they need to.
