Dawid 42bad68220 fix app crashing when reloads overlap (#46416)
Summary:
Regarding the [issue](https://github.com/facebook/react-native/issues/44755) where the app sometimes crashes due to race condition when two reloads overlap in unfortunate way. This PR fixes it in some way by introducing throttling on reload command. For now I set it to 700ms as I was still able to reproduce it on 500-550ms for provided repro in the issue. The problem may still happen for bigger apps where reload may take more time to finish.
