Summary:
This adds `react-native/metro-config` to the monorepo build tool and emits the missing typescript declarations.
Right now, we do have typescript declarations on `metro-config`, but not `react-native/metro-config`. Which makes everything a bit harder extend from "[the default React Native metro config](https://github.com/facebook/react-native/pull/36502)" in Expo.
> Note, I also added the same `exports` block from `react-native/dev-middleware` for conformity.
One open question here is, why aren't we exporting _all_ helper functions from `metro-config`? To me, its a bit weird that we need both `metro-config` _and_ `react-native/metro-config` as `loadConfig` isn't exported.

Over in React Native macOS land, I opened https://github.com/microsoft/react-native-macos/pull/2030 to update our mono repo to use Yarn 4. As a side effect, all the `package.json` files are formatted as a side effect of running `yarn install`. So that React Native macOS doesn't maintain this diff (and because they should only be good / no harm), let's upstream the formatting changes.

Pull Request resolved: https://github.com/facebook/react-native/pull/41219
Bump to the latest Metro release. This includes minor breaking changes to Metro subpackages that should *not* be visible to RN users.
Metro release notes: https://github.com/facebook/metro/releases/tag/v0.80.0
## Moving to unpinned versioning
Metro is a multi-package project, and not pinning to an exact version means multiple versions of `metro*` packages may appear in an RN project.
This isn't unusual in the NPM ecosystem and *shouldn't* be a problem, but historically has caused issues (eg https://github.com/facebook/react-native/issues/34714, https://github.com/facebook/metro/issues/1017). The root cause of all of these issues, as far as we know, was fixed in https://github.com/facebook/metro/commit/6d46078e74ae9a43aa90bed46dbd6610e2696cd0, a bug where Node hierarchical resolution was effectively sidestepped via a relative worker path, resulting in a mismatch between transformer and host process.
In addition, the fact that `react-refresh`, `metro-react-native-babel-transformer` and `metro-react-native-babel-preset` are now fully moved into the `react-native/` scope and versioned with React Native means there are no circular dependencies between React Native and Metro, explicit or implicit, and we're much more clearly decoupled.
So, we're moving to caret versioning to allow React Native users to pick up Metro fixes and features without requiring React Native releases and user upgrades.

Upgrade Metro dependencies to 0.79.1 in `react-native`
This includes Metro breaking changes for disabling global package resolution by default and adds features like: Haste packages, enable resolution through symlinks and passing custom customTransformOptions and customResolverOptions to bundle_build_started log event so as to refine the bundling message. It also fixes arbitrary transformation of Babel plugins during registration in `metro-babel-register` and fixes "unexpected null" crash when handling a batch of file changes and symlinks with indirections.

## Context
### React Native Metro config → React Native repo (https://github.com/facebook/react-native/pull/36502)
We (the React Native team) are aiming to relocate the default Metro config for React Native out of `react-native-community/cli-plugin-metro` and **into the React Native repo + app template** as a new `react-native/metro-config` package.
This is the first (and minimum viable) phase we can ship to separate the release process of Metro from RN CLI in order to reduce coupling and iterate faster for our users.
**See full motivation, design, and test plan (which previewed the CLI bump) here: https://github.com/facebook/react-native/pull/36502**
## Changes
NOTE: This PR is pending the inclusion of a bump to `react-native-community/cli`, and will be sequenced after https://github.com/react-native-community/cli/pull/1875 is merged.
- Upgrade `react-native-community/cli` to `11.0.0`, upgrade all `metro` packages to `0.76.0` (version distributed in this CLI release).
- Update the `metro.config.js` file in `packages/react-native/template/`.
- Now merges defaults from `react-native/metro-config`, and can be used with CLI >= 11.0.0.
- Update the `metro.config.js` files for `packages/react-native/` and `packages/rn-tester/` (these are integration test locations).
- Now merges defaults from `react-native/metro-config`, and can be used with CLI >= 11.0.0.
Changes to `react-native/metro-config` — `0.72.1` (prepared but not depended on yet):
- Export `mergeConfig` util (removing direct `metro-config` dependency in consuming projects).
- Explicitly depend on `metro-react-native-babel-transformer` and `metro-runtime` (transitively included today).
