[Kernel] Add trition.autotune to address the high latency overhead of punica kernels

[congcongchen123]

Now with Phi-4-multimodal-instruct merged into main, we would like to have another PR to address the high latency overhead we have observed for Phi4-multimod when using LoRA.

Benchmark results with this PR:
ttft: time to first token (in seconds)
tbt: time between token (in seconds)

👋 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 your contribution, have you tested the performance of autotune on models like llama?

Nope, I am not familiar with the llama family of models that use LoRA. Do you know any of those?

Thanks!

I'll hand it over to @jeejeelee as he is more familiar with these kernels.
