sync: support mpsc send with `&self` (#2861)
Updates the mpsc channel to use the intrusive waker based sempahore.
This enables using `Sender` with `&self`.
Instead of using `Sender::poll_ready` to ensure capacity and updating
the `Sender` state, `async fn Sender::reserve()` is added. This function
returns a `Permit` value representing the reserved capacity.
Fixes: #2637
Refs: #2718 (intrusive waiters)
