add WASIp2 TODO comments

// TODO #1: Add a public, WASIp2-only API for registering
// `wasi::io::poll::Pollable`s directly (i.e. those which do not correspond to
// any `wasi-libc` file descriptor, such as `wasi:http` requests).
//
// TODO #2: Add support for binding, listening, and accepting.  This would
// involve adding cases for `TCP_SOCKET_STATE_UNBOUND`,
// `TCP_SOCKET_STATE_BOUND`, and `TCP_SOCKET_STATE_LISTENING` to the `match`
// statements in `Selector::select`.
//
// TODO #3: Add support for UDP sockets.  This would involve adding cases for
// the `UDP_SOCKET_STATE_*` tags to the `match` statements in
// `Selector::select`.
