This PR adds support for System Resource Affinity Table (SRAT) and may fix #46. I have not tested this for correctness so I'll mark it as draft for now.

I wrote this because we want to acquire the affinity (or topology) information of hardwares to support NUMA platform in our project. Another follow-up PR for System Locality Information Table (SLIT) is on its way.

I've tested this against our project and it seems OK. Now ready for review.

@azongchang I noticed you reviewed this PR while it was still draft. So maybe you are interested in the change? It would be great if you could test it against your need or review it again since it's now marked ready. Thank you.

@jellllly420 Thanks for reaching out! I did review the PR earlier because I currently focused on preparing NUMA architecture for a Rust OS. However, I’m still in the early stages of that work, so I won’t be able to test this change comprehensively or provide a detailed review in the near future.

Friendly ping @IsaacWoods.
