`connect_timeout` is used twice in wasmtime-wasi-http's outgoing handler

As mentioned in #8085, the `connect_timeout` is used to timeout both the initial tcp connection, and the `handshake` result from hyper. We likely only need the first timeout on the tcp connection, but it would be good to validate this.

Concretely, we can probably remove the timeout uses from these two places in `types.rs`:
