Fix failing XCLIPModelIntegrationTest

[Sai-Suraj-27]

What does this PR do?

Fixes failing XCLIPModelIntegrationTests.

self.get_attributes() will not return all the processor instance attributes, for example in case of x_clip because video_processor is added like this.

processor = XCLIPProcessor.from_pretrained(
    "microsoft/xclip-base-patch32", size=180, crop_size={"height": 180, "width": 180}
)
processor.get_attributes()
# ['image_processor', 'tokenizer']

Iterating directly over the attribute_to_kwargs in __call__ will check for all types at run-time.

Code Agent Policy

The Transformers repo is currently being overwhelmed by a large number of PRs and issue comments written by
code agents. We are currently bottlenecked by our ability to review and respond to them. As a result,
we ask that new users do not submit pure code agent PRs at this time.
You may use code agents in drafting or to help you diagnose issues. We'd also ask autonomous "OpenClaw"-like agents
not to open any PRs or issues for the moment.

PRs that appear to be fully agent-written will probably be closed without review, and we may block users who do this
repeatedly or maliciously.

This is a rapidly-evolving situation that's causing significant shockwaves in the open-source community. As a result,
this policy is likely to be updated regularly in the near future. For more information, please read CONTRIBUTING.md.

• I confirm that this is not a pure code agent PR.

Hmm, this feels like a very core change for one model. cc @zucchini-nlp maybe?

Okayy, even now when looping through self.get_attributes() we are again making sure that it exists in attribute_to_kwargs, so directly looping through attribute_to_kwargs will not cause any new issues, hopefully.

Also, found tvp processor to be similar.
