Also includes a test for a type created from an ephemeral PyType_Spec.
(The original design assumed PyType_Spec structs would be static, but dynamic ones are useful and used in the wild.)

For what its worth: These changes look good to me (and a very nice test!). I could wonder if it may still be sensible to point intoht_name since the name is probably identical except that it starts after the first .? (EDIT: Sorry wrong way around of course)
(My first thought was also a flag, but if we have to worry about users mutating it, that is indeed not an option.)

LGTM! I left some minor remarks. The added refactoring also looks good.

Thank you for the reviews!

@seberg You're retracing my thoughts :) I tried both pointing into ht_name and a flag, and it's very frustrating that they don't work :)
