Perform cleanup when ReactApplicationContext is destroyed

Summary:
## Description
When we reload the app, `ReactApplicationContext.destroy()` is called. This method calls `CatalystInstanceImpl.destroy()`, which (on the NativeModules thread) calls `NativeModuleRegistry.notifyJSInstanceDestroy()`, which loops over all its `ModuleHolder`s, and calls `ModuleHolder.destroy()`, each of which call their NativeModule's `onCatalystInstanceDestroy()` method.

TurboModuleManager is a `JSIModule`, so it also has its `onCatalystInstanceDestroy()` method called when the `ReactApplicationContext` is destroyed. But `TurboModuleManager.onCatalystInstanceDestroy()` doesn't do anything. Instead, at the very least, it should call `onCatalystInstanceDestroy()` of all NativeModules.
