Exception: Serialization of 'Closure' is not allowed

Problem/Motivation

When uploading a file through an image effect form (Drupal\image\ConfigurableImageEffectBase), the AJAX request breaks with the following error:

Exception: Serialization of 'Closure' is not allowed

I was able to track down the cause: the request_stack service being serialized. I think the root cause is actually a Symfony\Component\HttpFoundation\File\UploadedFile object in the current request.

Steps to reproduce

Create a configurable image effect with a managed_file in its configuration form.

Proposed resolution

I fixed this issue by including DependencySerializationTrait in ImageEffectBase and by directly injecting logger.channel.image instead of getting it from the logger factory, since this way the logger can be serialized.
