Summary:
When a native module registers itself as a lifecycle event listener, ReactContext will immediately call `onHostResume` if the activity is already in a resumed state. We rely on this behavior for things like NativeAnimatedModule, which only enqueues the frame callback in onHostResume. However, ReactContext only does this if `hasActiveCatalystInstance()` returns true - which makes sense, because we don't want to notify listeners if the instance has been destroyed. But in bridgeless mode, `hasActiveCatalystInstance` returns false, and we never call `onHostResume` in this case.
This diff fixes an issue where native driver animations don't work the first time you navigate to a screen with bridgeless mode enabled.

Summary:
`UIManagerHelper.getUIManager()` relies on the bridge (CatalystInstance) to get the proper UIManager depending on which renderer is being used. Unfortunately, this means it will always return null in bridgeless mode, where the CatalystInstance doesn't exist. This diff replaces the implementation of `BridgelessReactContext.getJSIModule()` to return the FabricUIManager from the ReactHost/Instance.

Summary:
## Description
When the TurboModule and the NativeModule systems are alive at the same time, after RN cleanup, if a TurboModule is required, we return `null` from TurboModuleManager. This causes `CatalystInstanceImpl.getNativeModule` to do a lookup on NativeModule registry, which throws an `AssertionError`, because the TurboModule isn't found. Instead of throwing an `AssertionError` from `CatalystInstanceImpl.getNativeModule`, this diff instead has that method return `null` in this particular case.
## Rationale
This should eliminate the crashes we're seeing in T46487253.
## Future action
In the future, we should guard `CatalystInstanceImpl.getNativeModule` with an `if (mDestroyed) return null;` statement. This'll ensure that if NativeModules are required after React Native has started cleanup, they'll be returned as `null`. Right now, we either return the destroyed NativeModule object, or create/initialize the NativeMoulde and return it, which is wrong.

Summary:
In bridgeless mode, the CatalystInstance doesn't exist, but we still need to be able to access the sourceURL in SourceCodeModule (which is needed to render the images in LogBox warnings and errors). This diff adds a new API for getting the sourceURL directly from ReactContext, instead of having to call context.getCatalystInstance().getSourceURL(), and updates SourceCodeModule to use it.

Mostly for easing open-source migration and not making a backwards-incompatible change (yet), we'll set this to false by default. Every app can opt-in to this if wanted but it's not necessary. This change is part of experiments surrounding more-aggressive teardown for Fabric and Bridgeless mode.
Changelog: [Internal] - This has the effect of (by default) disabling the previous diff which caused ReactContext teardown to always set mCatalystInstance to null. Now that is opt-in behavior and off by default, so it's not longer a breaking change.

Summary:
Step 1 in removing the dependency on ReactContext from GuardedRunnable and other related classes. These are extensively by native modules and view managers, so in order to remove the bridge dependency from those modules we'll need to first decouple these classes from ReactContext. It turns out they only need ReactContext for its handleException method, which delegates out to product code. For backwards compatibility I'm exposing another NativeModuleExceptionManager in ReactContext that simply wraps its handleException method (since this interface already does everything we need).
I figured I'd keep around an extra constructor that still uses ReactContext for now instead of trying to migrate everything over at once.

Summary:
This mechanism is heavily abused inside of the react-native and inside of the various native modules.
The main problem is that people don't remove their listeners and as result, we have memory leaks.
Some modules like UIManager, NativeAnimatedModule have resources holding Activity context. Those modules are held through a pretty long chain of dependencies.
In order to allow GC to collect those listeners, I replaced the CopyOnWriteSet by WeakHashMap and synchronized access. It is not such a big deal in terms of performance as those listeners are not called/modified too frequently but this prevents hard to debug memory leaks.

Summary:
**Motivation**
I'm working on a project that uses React Native and needs to add direct synchronous bindings to native stuff through the JavaScriptCore C API. This is because it's performance-sensitive and would benefit from the quickest JS->C path. It does this using cross-platform C++ code that works on both iOS and Android. Most of the infrastructure for getting access to the JSC context is already in React Native actually, just had to add a few more things.
(lexs you mentioned to tag you in this pull request)
**Test plan**
Modify the JavaScriptCore context through the `JSContextRef` returned (eg. add an object at global scope) and verify that it exists in JavaScript.
