[BUG] Resized Webp images generated by Timber/ImageHelper::towebp and Timber/ImageHelper::resize filter are not deleted along original image

[montagmorgens]

Expected Behavior

When I delete an image from the WP media library, I expect that all derivative image files that were created by Timber image filters are deleted as well.

Actual behavior

Images that were created by a combination of resize and towebp filters are not deleted from the file system.

Steps to reproduce behavior

1. Create image in Twig: image.src|towebp|resize(100,100)
2. Delete the image from the WP media library

This shouldn't be implemented before this is implemented, or the wrong images might be deleted: #2850
