Implements:
- https://wg21.link/P1132R8 - `out_ptr` - a scalable output pointer
abstraction
- https://eel.is/c++draft/smartptr.adapt - 20.3.4 Smart pointer adaptors
- https://wg21.link/LWG3734 - Inconsistency in `inout_ptr` and `out_ptr`
for empty case
- https://wg21.link/LWG3897- `inout_ptr` will not update raw pointer to
0
