[libc-commits] [libc] [libc] document supported os ranges (PR #118863)

[Schrodinger ZHU Yifan via libc-commits]

https://github.com/SchrodingerZhu created https://github.com/llvm/llvm-project/pull/118863

LLVM-libc does not guarantee backward compatibility with operating systems that reaches their EOL.
Compatibility patch for obsolete operating systems will not be accepted.

For Linux, we support kernel versions as listed on [kernel.org](https://kernel.org/>), including
``longterm``, ``stable``, and ``mainline`` versions. We actively adapt new features
from ``linux-next``.

For Windows, we support products within their lifecycle. Please refer to 
[Search Product and Services Lifecycle Information](https://learn.microsoft.com/en-us/lifecycle/products/?products=windows) for more information.
