Update sequence.py to prevent LogitsProcessor objects from being deepcopied

[loginaway]

Deepcopying sampling_params that include LogitsProcessor might lead to OOM. This has been an old issue here:

#3087

and the previous commit #3099 fixed this issue in vllm/engine/llm_engine.py

However it is re-occurring in vllm/sequence.py. This commit is trying to fix this again.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

🚀

Thanks for the fix.

Fix the pre-commit, also is it a way to add a unittest to guard this?
