  [Clang] Fix crash when recovering from an invalid pack indexing type. (#80652)

If the pattern of a pack indexing type did not contain a pack, we would
still construct a pack indexing type (to improve error messages) but we
would fail to make the type as dependent, leading to infinite recursion
when trying to extract a canonical type.
