We still crash if we detect a cycle, which we check for more explicitly now; and we still always crash in non-Fabric. But if we detect a partial graph in Fabric,
we warn instead of crashing. We also print the state of the graph before crashing/warning, to assist in debugging in production.

Summary:
This diff fixes a ConcurrentModificationException that is thrown when registering events in React Native.
This bug was introduced by D22483508 (https://github.com/facebook/react-native/commit/80f13412e548c8666b6ad770e6d3d5c54a717bc2), before event listeners were registered in the NativeModule Thread, now they are registered in the UI Thread.
As part of this diff I change the type of mListeners variable to use CopyOnWriteArrayList instead of ArrayList because this variable is accessed from different threads. This will prevent the exception to happen, but additionally we need to verify if the change of threading made in D22483508 (https://github.com/facebook/react-native/commit/80f13412e548c8666b6ad770e6d3d5c54a717bc2) will cause any other issue (e.g. events not being delivered becuase the listeners are registered too late in the UI Thread)

Apparently it's possible for `!isEmpty()` to be true and `peek` to be non-null, but for `poll()` to be false. It doesn't really make sense to me, and I don't have a repro, but that's what logs are showing.
I suspect a teardown race condition or /maybe/ a Fabric/non-Fabric handoff race condition. Neither of those make a ton of sense, though.
The mitigation is fairly straightforward: we are just much more cautious with how we treat the queue and assume everything could be null.
This impacts Fabric and non-Fabric equally.

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:
There are potential race conditions in the old implementation that could result in operations being executed out-of-order when the user transitions between Fabric/non-Fabric screens.
Specifically, if the non-Fabric path queues up a batch of operations to execute on the next UI tick, it is possible that Fabric lifecycle events fire /before/ that next UI tick and synchronously execute a batch of animation operations on the UI thread, before their predecessors have executed.

Summary:
We need to instrument the following markers for TurboModules in Java:
- **Java:** moduleDataCreate
- **Java:** moduleCreate
**Problem:** Perf-logging can be on or off in production. This means that we have to guard every perf-logger call, which can be a bit tedious. Therefore, this diff introduces a Java class called `TurboModulePerfLogger`, which:
1. Enables perf-logging by accepting a `NativeModulePerfLogger` `jni::HybridObject` in its `enableLogging` method.
2. Exposes static methods that call into the `NativeModulePerfLogger`'s Java part, when perf-logging is enabled.
We actually have C++ markers as well:
- **C++:** moduleJSRequireBeginning
- **C++:** moduleJSRequireEnding
- **C++:** syncMethodCall
- **C++:** asyncMethodCall
- **C++:** asyncMethodCallExecution
Therefore, `TurboModulePerfLogger.java` also calls its native method `jniEnableCppLogging` to setup C++ TurboModule perf-logging.
TurboModule C++ logging is done via a similar setup (to Java), using `TurboModulePerfLogger.cpp`. The `jniEnableCppLogging` native method calls into `TurboModulePerfLogger::enableLogging` with the C++ part of `NativeModulePerfLogger`. Then, the TurboModules C++ infra uses the static methods on `TurboModulePerfLogger.cpp` to start/end markers.
