Remove reset() from the API of objects where creating a new instance is sufficient

[jan-kolarik]

This is a follow-up to #1678.

The goal is to review our reset() methods and identify those that provide no additional value compared to simply using the constructor. In these cases, I suggest dropping the reset() methods, as they require maintaining lists of objects (like vectors, maps, etc.) and their clearing can be handled automatically by the destructor.
