f8d63168 - [Clang] Fix a pack expansion bug in template argument deduction (#141547)

[Clang] Fix a pack expansion bug in template argument deduction (#141547) I think the intent of df18ee96206 was to substitute only those non-packs into a pack expansion type (e.g. `T` in `T::pack...`), so let's hold off pack expansions explicitly, in case there are calls coming from a substitution of pack expansion.
