Debug statistics conversion

[arves100]

Might be usefull to someone who wants to debug code with this engine (for example seeing if scripts are correct)

The original design relied on winapi windows, a simple approach would be exposing a Debug window with ImGui, which might also mean more thinking into imgui abstraction or something more decoupled/hardcoded.

Solution applied:
Created simple interfaces (Informater interfaces) that will be called/updated, GUI based updates with gstd panel will be pushed into DnhView, while ImGui/whatever other type will be pushed into the executer, this allows us to completely divide executer with the viewer.
Probably better versions of it will be created once more serious refactoring in the code will take place.
Future commits (currently wip on my PC as it doesn't build) will already contain this change.
This issue will be closed once such commits will be pushed.
