CLI start working without rnc/cli-server-api

When decoupling the community-cli-plugin from the @react-native-community/cli-server-api (#45311), a middleware stub was created to allow a runtime stub to be used in this case. This middleware should be used so as not to break when the optional cli-server-api dependency isn't present. Changelog: [General][Fix] - Fix npm react-native start when cli-server-api isn't installed Testing: Forced a runtime exception simulating the package not being dependent and was able to build rn-tester.
