Document aarch64 CPU support works

[ericcurtin]

I tested it recently in a Linux VM on macOS, works great! Although it could do with CI, I see silly bugs creep in sometimes.

Code Review

This pull request updates the vLLM V1 guide to document support for the aarch64 CPU architecture. The change modifies the hardware support table, adding aarch64 to the list of supported CPU architectures. This is a straightforward and valuable documentation improvement that accurately reflects the project's capabilities.

👋 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.

cc @mgoin do you know the status of MacOS support?

I didn't try macOS support FWIW. I tried a Linux VM on macOS and it worked great! podman-machine/krunkit in my case.

Needed this small fix at the time because at least on this hypervisor it couldn't do numa detection stuff:

#21115

ARM CI seems pretty simplified these days on github:

I do think Vulkan with macOS and MoltenVK (or even in Linux VMs via krunkit) could be really neat. Something that has been discussed with people like @rhatdan, @slp, @airlied , etc.

Vulkan solves problems as regards acceleration on a lot of hardware. And performs decently well:
