Move eslint/prettier config to packages/eslint-config-react-native (#23688)

Summary:
Basing on discussion from this issue - react-native-community/discussions-and-proposals#65 we moved ESLint/Prettier config to its own package inside packages directory.
At this moment we had to left all `eslint` dependencies in root `package.json` since `eslint-config-react-native` is not published yet.

[General] [Changed] - Move eslint/prettier config to packages/eslint-config-react-native
