Add a cros_async crate. This crate will house code using the new async/await features to be used by other parts of crosvm. Start the crate with a Future executor that runs tasks in a single thread and allows futures that block on system file descriptors.

cros_async: add uring_executor Add an executor, similar to `fd_executor`, except driven by io_uring instead of `PollContext`. This will allow for queueing actions instead of waiting for 'ready' from poll. This reduces the number of syscalls and increases the parallelism possible when doing IO.

cros_async: Make raw waker Send + Sync std::task::Waker unconditionally implements Send + Sync so the raw waker that we provide also must implement those traits. Switch to using an Arc<AtomicBool>. This also fixes an inconsistency where the waker was defined to be an Rc<Cell<bool>> but all the vtable functions were treating as an Rc<AtomicBool>. To reduce the vtable boilerplate use the ArcWake trait from the futures crate.
