Consider mentioning Manuel Drehwald's LLVM offload work in Ecosystem section

It's still very early days and I'm not sure if normal people can even try it out yet. But I find that approach interesting because if we can get it to work, from my understanding, it means we can share a large fraction of the work with LLVM's C/++/Fortran OpenMP 4 backends, and that gives us access to a much larger workforce than Rust-on-GPU has ever enjoyed so far. So I'm curious to see what it will lead us to.

As far as I know, the main way to track progress right now is to subscribe to this github issue.

找到網站的 Ecosystem 區段，並查看連結的 Rust project-goals issue，以了解 Manuel Drehwald 的 LLVM offload 工作目前的詳細情況。根據所參照的討論確認狀態與措辭，然後新增簡潔且準確的說明及連結；Ecosystem 區段應清楚反映這項工作，但不要誇大其成熟度。
