Fix local-cli assetRegistryPath and middlewares (#20162)

Summary:
This fixes some regressions with local-cli introduced in c4a66a89a28152cd4b81e2b0f80ab3aac34d6872.

- We didn't pass `assetRegistryPath` which caused the following error when loading the bundle:
```
error: bundling failed: Error: Unable to resolve module `missing-asset-registry-path` from `/Users/janic/Developer/react-native/RNTester/js/[email protected]`: Module `missing-asset-registry-path` does not exist in the Haste module map
```
- The middlewares were not added to the metro server. This causes some packager server features to fail. The one I noticed is that the /status endpoint didn't exist anymore which causes CI to fail and also Android to not load the bundle from the packager initially. The remote debugging feature was also broken.
