Implement saved window positioning per target (#53910)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53910

NOTE: Resubmission of D82236159 — The `electron-store` dependency is now replaced with a local implementation.

As titled. A long awaited quality of life improvement that we can now deliver with our desktop shell.

Window arrangements are saved per [`windowKey`](https://github.com/facebook/react-native/blob/da7bf9c54567aae62ff355b79e66f511cb382065/packages/dev-middleware/src/middleware/openDebuggerMiddleware.js#L193), mapping to each previously opened debugger target.

**Limitations**

- Does not save/restore macOS fullscreen app state.
