In lldb-dap tests, we sometimes spawn subprocesses directly but do not always correctly clean them up. This can cause some tests, like the `TestDAP_disconnect.test_attach` to hang and not properly respect timeouts. To fix this, I am passing the `lldbtest.Base.spawnSubprocess` helper to the adapter client so it can be used spawn subprocesses in a way that we can ensure they're cleaned up.
