Fix for loading state of Fast Refresh from user defaults (#29880)
Fix for loading state of Fast Refresh from user defaults (#29880)

Summary:
Disabling Fast Refresh won't be persisted when restarting the app.

I believe this regressed with https://github.com/facebook/react-native/commit/824e1711172d14a9373209bbae63d1ae50601625. In this commit `HMRClient.setup` will always be called with `enabled` being set true. This PR loads the _enabled_ state from the user defaults (as it was done before).

## Changelog

[iOS] [Fixed] - Enable Fast Refresh gets persisted across app launches

Pull Request resolved: https://github.com/facebook/react-native/pull/29880

Test Plan:
Without this change Fast Refresh is enabled on every app restart.

Tested with this change:
- Disabling Fast Refresh
- Restarting App -> Fast Refresh still disabled
- Enabled Fast Refresh again
- Restarting App -> Fast Refresh still enabled again
