[roll] Roll fuchsia [fuchsia-async] Prevent RWHandle wait explosion

RWHandle may end up installing an unbounded number of waiters on the
port because it allows the waiter installed for Rx to clear the signal
bit for Tx and vice-versa. Subsequent polls may end up adding more
waiters.

Fix by ensuring that only the waiter for the correct direction can clear
the signal bits cached in the receiver.

While I'm here, remove redundant arguments in `need_signal` so we better
encode the dual-waiter capabilities of RWHandle in the internal API.
