  [Clang] Don't assert non-empty packs for FunctionParmPackExprs (#107561)

`FunctionParmPackExpr`s are peculiar in that they have to be of
unexpanded dependency while they don't introduce any unexpanded packs.
So this patch rules them out in the non-empty pack assertion in
`DiagnoseUnexpandedParameterPack()`.

There was a fix #69224, but that turned out to be insufficient.

I also moved the separate tests to a pre-existing file.
