  [Clang] SFINAE on mismatching pack length during constraint satisfaction checking (#101879)

If a fold expanded constraint would expand packs of different size, it
is not a valid pack expansion and it is not satisfied. This should not
produce an error.

Fixes #99430

(cherry picked from commit da380b26e4748ade5a8dba85b7df5e1c4eded8bc)
