Add test to ensure that `connect_timeout` is correctly passed around

The following diff should be applied to ensure that the `connect_timeout` variable is correctly passed into the `handle` function.

This code was removed in https://github.com/bytecodealliance/wasmtime/pull/8085#discussion_r1521942861 due to a failure on Windows MinGW x86_64.
