  [clang][Sema] Avoid non-empty unexpanded pack assertion for FunctionParmPackExpr (#69224)

Closes https://github.com/llvm/llvm-project/issues/61460.

We have FunctionParmPackExpr that serves as the unexpanded expression
but from which the visitor collects none, which may lead to assertion
failure during the template instantiation.
