fa898e6836a8fc2c7b6c8c15ad21818b16a89863 refactor: Print verbose serialize compiler error messages (MarcoFalke)
Pull request description:
Currently, trying to serialize an object that can't be serialized will fail with a short error message. For example, the diff and the error message:

This is fine. However, it would be more helpful for developers and more accurate by the compiler to explain why each function is not selected.
Fix this by using C++20 concepts where appropriate.
