Move Community CLI discovery config into plugin package (1/2) (#58670)

Summary:
Replaces #57352.

Self-register commands from the `community-cli-plugin` package via `react-native.config.js` — meaning we can remove the redirect within `packages/react-native/react-native.config.js`.

Progress towards removing `community-cli-plugin` as a direct dep of `react-native`, and paired with react-native-community/template#235.

RNTester and HelloWorld list `react-native/community-cli-plugin` in `devDependencies`, as the template now does (react-native-community/template#235).

Changelog:
[General][Breaking] - `react-native/community-cli-plugin` will no longer be auto-detected from `react-native`. It must now be specified in `devDependencies`.

Pull Request resolved: #58670

Test Plan:
Compared `react-native config` output with `react-native-community/cli` 20.2.0.

**RNTester**

- ✅ Commands, platforms, and project config are unchanged from `main`
- ✅ Removing the new `react-native/community-cli-plugin` devDependency drops `bundle`, `start`, `spm`, and `codegen`, so they are registered by plugin discovery

**Template-shaped app** (plugin in `devDependencies`, no project `react-native.config.js`)

- ✅ `bundle`, `start`, `spm`, and `codegen` are registered
