runtime: elide instantiated types in tracebacks

They tend to be things like ".shape.int" which are noisy, if not
otherwise confusing.

It would be nice to somehow print the real instantiations here, but that
requires keeping track of the dictionary argument so the instantiating
types could be found. One day, maybe, but not today.

Fixes #48578
