test: split wasi tests

Move the child process code into a fixture and split the test so that it can be run in parallel and it's easier to identify where the failure is coming from. Also use the spawnSyncAndExitWithoutError() utility so that the test shows complete information on failure. Instead of marking all the wasi tests as flaky, only mark the wasi-poll one which is flaking in the CI now.
