[C23][Parser] Accept single variadic parameter function declarator in type name (#145362)
Fixs: https://github.com/llvm/llvm-project/issues/145250.
This PR makes clang accept single variadic parameter function declarator
in type name.
Eg.
```c
int va_fn(...); // ok
// As typeof() argument
typeof(int(...))*fn_ptr = &va_fn; // ok
// As _Generic association type
int i = _Generic(typeof(va_fn), int(...):1); // ok
```
