Moti Zilberman ab1af2844b Support Fusebox shell experiment in OSS without a custom BrowserLauncher (#53435)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53435

Changelog: [Internal] Support setting `enableStandaloneFuseboxShell: true` in OSS with no custom `BrowserLauncher`

Makes it possible for frameworks to enable the React Native DevTools standalone shell in open source by passing `unstable_experiments: {enableStandaloneFuseboxShell: true}` to `createDevMiddleware()`.

When this experiment is enabled:

* The RNDT shell binary will be prefetched in the background as soon as the dev server starts (into a local cache managed by [DotSlash](https://dotslash-cli.com/)).
* If prefetching is successful, then "Open DevTools" actions will be handled by launching the RNDT frontend in the standalone shell, instead of in Chrome/Edge.
* If prefetching is not successful, then we'll notify the user about the error, and "Open DevTools" will continue to be handled by Chrome/Edge, as before.
* If the user attempts to open DevTools more than once for the same app, the standalone shell will reuse the existing window (as opposed to the current behaviour of always creating a new Chrome/Edge window).
* The appropriate DevTools window will automatically foreground itself upon pausing on a breakpoint.
