add more mixed tests, with c-cast, reinterpret cast, const_cast.

Add test with cast to `const void*`, and also test with functional cast would be needed like:

```
struct A
{
   A(void*);
};

return A(static_cast<void*>(ptr)); // need to be checked if this trigger CXXFunctinalCast with ConstructorConversion kind.
```
