In `async` functions, instead of completing the function's `Future` via `Completer`, do it directly. This should be slightly more efficient as we eliminate a layer of indirection when completing. Move reading the `_future` field of `_AsyncSuspendState` to the completion functions, to avoid adding a `struct.get`s at each call site. In ACX demo, makes the final binary 0.1% smaller (13,689 bytes). Fixes #60719. Issue: https://github.com/dart-lang/sdk/issues/60719 CoreLibraryReviewExempt: Wasm-specific change.
