Adds support for async service scope in request executor

[PascalSenn]

In case you add a service to the DI that only has implemented IAsyncDisposable you will get the following error:

'YourType' type only implements IAsyncDisposable. Use DisposeAsync to dispose the container.

Instead of creating a AsyncServiceScope on every resolver execution, it should be enough to just check if the scope implements IAsyncDisposable:
