Detr preprocessor fix
# What does this PR do?
Ensures that `DetrFeatureExtractor` doesn't preprocess input `images` and `annotations` in-place by creating deep copies of inputs within `DetrFeatureExtractor.__call__()`.

`YolosFeatureExtractor` has the same issue and will be fixed in a separate PR.

Fixes #[18987](https://github.com/huggingface/transformers/issues/18987)
