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.

Summary:
Currently the error messages lead users to assume that all problems are because we're trying to use the ReactContext too early; it could be because we're using it too late, after it's been destroyed. Because of D17944723, it could be because we're accessing too late, after teardown.

Summary:
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.

Summary: Provide a base `HeadlessJsTaskService` class that can be extended to run JS in headless mode in response to some event. Added `HeadlessJsTaskEventListener` for modules that are interested in background lifecycle events, and `HeadlessJsTaskContext` that basically extends `ReactContext` without touching it. The react instance is shared with the rest of the app (e.g. activities) through the `ReactNativeHost`.

Summary: Utilizes the build time annotation processor ReactModuleSpecProcessor that creates ReactModuleInfos for modules annotated with ReactModule and listed in the ReactModuleList annotation of LazyReactPackages. This way we don't have to instantiate the native modules to get the name, canOverrideExistingModule, and supportsWebWorkers values of the native modules. In the NativeModuleRegistry, we either store these ReactModuleInfos inside of a ModuleHolder or if we can't get the ReactModuleInfo for a specific module we instantiate that module to get the values (as we previously did) to store in a LegacyModuleInfo.

Summary:
The Android lifecycle is weird: turns out `onActivityResult` is called before `onResume`. This means `getCurrentActivity()` could return the wrong instance, or `null` if the activity was destroyed. To give developers access to the Activity receiving the result (which is also about to become the current activity), pass it as an argumento the listener.
Fixes github issue #8694.

Summary: It doesn't make sense to clear mCurrentActivity in onHostPause -- we're not going to leak a paused activity. Only keeping it around after onDestroy could lead to leaks. This allows us to check the source of lifecycle events and only send them if they come from the current activity (upcoming diff).
