AIAdd a new I/O utility extension method
- Add trait method to the appropriate ext trait (AsyncReadExt, AsyncWriteExt) in tokio/src/io/util/
Add support for a new event notification backend
- Create platform-specific module (e.g., tokio/src/io/epoll.rs or extend tokio/src/io/uring/mod.rs) with syscall bindings
- Implement readiness polling logic compatible with poll_evented and AsyncFd abstractions
- Conditionally enable via feature flag in tokio/Cargo.toml and add cfg guards in lib.rs
Add platform-specific I/O operation (uring example)
- Expose through tokio/src/io/uring/mod.rs and wire into tokio/src/io/mod.rs with feature gate
