to Fix #1425
When I want to register a non abstract class, I will use
GDREGISTER_CLASS()or other macros, But I registered the abstract class throughGDREGISTER_CLASS()(possibly because forgot to implement the pure virtual methods), and there were no compilation errors, which would give me some misunderstandings.It is because
if constexpr (!std::is_abstract_v<T>)determined that this class is an abstract class and did not compilememnew(T).May necessary to confirm that when using GDREGISTER_CLASS(), the
memnew(T)must compile. Therefore, when I mistakenly register an abstract class byGDREGISTER_CLASS(), the compiler will give error message.
