Log create(...) functions

[upsj]

Logger has a polymorphic_object_create_started/completed event, but it only works based on PolymorphicObject::create_default, not any other functions like the one provided by EnableCreateMethod. To change this, we could add another overload to the event that only gets passed the executor in _started and only the created object in _completed and gets called conditionally (if the first parameter is an executor) in EnableCreateMethod::create and manually in all the create_const functions.
