Some managers may use the environment in the destructors. Setting them to
nullptr may lead to nullptr dereference when the object is still alive and can
be accessible. But after object is destructed it's UB anyway to dereference
nullptr or a dangling pointer.
Engine controls lifetime of managers therefore it should own them. Environment
is only access provider.
This allows to avoid redundant virtual calls and also some functions from
managers base classes can be removed if they are used only by Engine.

Instead of explicit work queue stop before any possibly used engine manager
is destructed. Based on an assumption that any engine manager can be destructed
independently from the work queue destruction. This model is already used in
CellPreloader that conflicts with explicit work queue stop.
After the work queue is requested to be stopped, any client waiting for a not
started work item to be done will wait forever because the work item is dropped
from the queue. Therefore either clients should not wait for own work items to
be completed in destructor or the work queue should not drop items before
clients are destructed. Other approaches are possible but are not considered
due to increasing complexity.
CellPreloader already tries to wait for all created work items to be done so
keep it that way and extend the model to AsyncScreenCaptureOperation and Scene.
Additionally abort all scheduled work items when owner is destructed. This
prevents a long exit when multiple screenshots are scheduled right before
exiting the game.
