Changelog: [Internal][iOS] Modularlize RCTBridgeModule.h 3/n - Move RCTTurboModuleRegistry.h to its own file in ReactInternal target
# Why clean up RCTBridgeModule.h?
Clean up one unnecessary import of RCTBridgeModule.h.
RCTBridgeModule includes a lot of header files, and this header is imported everywhere. The ultimate goal is that files (especially React Native infra files) should only import only what they need and not import the entirety of RCTBridgeModule.h whenever possible.
This way, certain headers that are Bridge-only can be compiled out of the new architecture with a flag.

Summary:
In https://github.com/facebook/react-native/pull/32695, the `Performance.now()` implementation changed to use unix epoch timestamps instead of a monotonic clock.
This is problematic, because it means that performance measurements get skewed if the device clock changes between two measurements.
With this change, the clock is now monotonic (and the implementation stays consistent between platforms).

Summary:
Changelog: [iOS][Internal] Refactor CxxBridge: Introduce RCTBridgeModuleDecorator to attach synthesize ivars to RCTTurboModules, in Bridge mode
This doesn't change any logic. RCTBridgeModuleDecorator was created to consolidate several nearly identical implementations of the `attachInteropAPIsToModule` method to one place.
Most importantly, it allows us to attach interop APIs in RCTBridgeModuleDecorator to RCTViewManagers in diff 4/4, using `attachInteropAPIsToModule`. Before this stack, these four synthesize ivars in RCTViewManagers are nil in Bridgeless mode, and point to instances in Bridge mode.
# Context
These are used in RCTBridgeModules to access APIs for view managers. These APIs are necessary and compatible with Bridgeless mode.
* synthesize viewRegistry_DEPRECATED
* synthesize bundleManager
* synthesize callableJSModules
* synthesize moduleRegistry

Summary:
I've noticed that the `performance.now()` implementations differ on iOS and Android.
iOS:
```objc
PerformanceNow iosPerformanceNowBinder = []() {
// CACurrentMediaTime() returns the current absolute time, in seconds
return CACurrentMediaTime() * 1000;
};
```
Android:
```c++
double reactAndroidNativePerformanceNowHook() {
auto time = std::chrono::steady_clock::now();
auto duration = std::chrono::duration_cast<std::chrono::nanoseconds>(
time.time_since_epoch())
.count();
constexpr double NANOSECONDS_IN_MILLISECOND = 1000000.0;
return duration / NANOSECONDS_IN_MILLISECOND;
}
```
For consistency, I thought why not just use the same implementation on both iOS and Android.
It also seems more logical to use Chrono on iOS, since it has nanosecond precision and we just multiply it to milliseconds, whereas `CACurrentMediaTime` multiplies to seconds, and we divide it down to milliseconds again.

Summary:
## Context
RCTModuleRegistry allows NativeModules to require other NativeModules, regardless of if they're using the old or the new system.
## Problems
Currently, the TurboModuleManager owns the RCTModuleRegistry. This results in the following ownership diagram:
{F660246242}
As you can see, for the bridge case, we're maintaining two *different* RCTModuleRegistry objects, both of which maintain a backward reference to the bridge and the TurboModuleManager.
## Changes
If we stop having TurboModuleManager own the RCTModuleRegistry, and just have React Native's initialization layer attach it to NativeModules, then we can simplify the above ownership diagram to this:
{F660246285}
## Benefits
- Less complicated design for RCTModuleRegistry
- RCTModuleRegistry understands the old and the new NativeModule system. So, it makes more sense for RCTModuleRegistry to be owned by the bridge, which also understands the old and the new NativeModule system.
- **Actual Motivation:** This allows us to start exporting RCTModuleRegistry from the bridgeless core, which is safer than leaking the TurboModuleManager from the bridgeless core. Diffs incoming.

Introducing LeakChecker. A tool that checks if all native components have been cleaned up when surface is stopped.
**Known shortcomings**:
- LeakChecker is only enabled in debug builds and the existence of leaks is logged to console.
- For now, Leak Checker looks at N-1 screen. This is intentional as there is a known limitation of React that doesn't free up all shadow nodes when surface is stopped. Because of this, the use of LeakChecker is not intuitive and I'll work with React team to try to work around this.
- It doesn't help locating the leak, it only informs that leak is present. I'll be looking into ways to help locate the leak.

This diff adds that filtering for modules returned from extraModulesForBridge.
NOTE: NativeModule initializers can still perform side-effects. So, it's still best to not create the TM-compatible NativeModule inside extraModulesForBridge. This diff just adds an additional layer of defense within the bridge.

Summary:
Adding another method to ReactMarker to log a marker with both a tag and an instanceKey. The instanceKey is used to attach the event to the correct marker instance - this is used already in Java, but not in C++ yet.
The way that ReactMarker is currently set up makes this change a little more complex/confusing. For some reason I'm not totally clear on, we're using C-style exports with some platforms-specific ifdefs in ReactMarker.h (even though the impl is .cpp?). And we swap out the implementation for `logTaggedMarker` at runtime in platform-specific code (JReactMarker and RCTCxxBridge).
In this diff, I just add a new function alongside `logTaggedMarker`, `logTaggedMarkerWithInstanceKey`. I did it this way because I figured modifying `logTaggedMarker` to add an argument would be a breaking change.

Summary:
Microsoft’s RN for macOS fork supports the Hermes engine nowadays https://github.com/microsoft/react-native-macos/pull/473. As a longer term work item, we’ve started moving bits that are not invasive for iOS but _are_ a maintenance burden on us—mostly when merging—upstream. Seeing as this one is a recent addition, it seemed like a good candidate to start with.
As to the actual changes, these include:
* Sharing Android’s Hermes executor with the objc side of the codebase.
* Adding a CocoaPods subspec to build the Hermes inspector source and its dependencies (`Folly/Futures`, `libevent`).
* Adding the bits to the Xcode build phase script that creates the JS bundle for release builds to compile Hermes bytecode and source-maps…
* …coincidentally it turns out that the Xcode build phase script did _not_ by default output source-maps for iOS, which is now fixed too.
All of the Hermes bits are automatically enabled, on macOS, when providing the `hermes-engine-darwin` [npm package](https://www.npmjs.com/package/hermes-engine-darwin) and enabling the Hermes pods.

Summary:
## Context
1. In FBReactModule jsExecutorForBridge, we asynchronously initialize a list of TurboModules on the main queue: https://fburl.com/diffusion/i56wi3px
2. After initializing the bridge, we start executing the JS bundle, here: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/React/CxxBridge/RCTCxxBridge.mm#L414-L417. Since bridge initialization knows nothing about TurboModule eager initialization, this happens concurrently with 1, and starts requiring NativeModules/TurboModules on the JS thread.
## The Race
1. Both the main thread and the JS thread race to create a TurboModule that requires main queue setup.
2. The JS thread wins, and starts creating the TurboModule. Meanwhile, the main thread blocks, waiting on a signal here, in RCTTurboModuleManager: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm#L430
3. The JS thread tries to dispatch_sync to the main queue to setup the TurboModule because the TurboModule requires main queue setup, here: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm#L402
4. We deadlock.
## The fix
Succinctly, NativeModule eager initialization finishes before execute the JS bundle, but TurboModule initialization doesn't. This diff corrects that mistake.
The changes in this diff:
1. The RN application via the TurboModuleManager delegate can now optionally provide the names of all eagerly initialized TurboModules by implementing two methods `getEagerInitModuleNames`, `getEagerInitMainQueueModuleNames`.
2. The TurboModuleManager grabs these two lists from the delegate, and exposes them to its owner via the `RCTTurboModuleRegistry` protocol.
3. The RCTCxxBridge, which already owns a `id<RCTTurboModuleRegistry>` object, uses it to eagerly initialize the TurboModules in these two lists with the correct timing requirements.
This is exactly how we implement eager initialization in Android.
**Note:** Right now, phase one and two of TurboModule eager initialization happen after phase one and two of NativeModule eager initialization. We could make the timing even more correct by initializing the TurboModules at the exact same time we initialize the NativeModules. However, that would require a bit more surgery on the bridge, and the bridge delegate. I think this is good enough for now.

Summary:
## Context
- If a NativeModule requires main queue setup, its `constantsToExport` method is executed on the main queue.
- In the TurboModule system, `constantsToExport` or `getConstants` is treated like a regular synchronous NativeModule method. Therefore, it's always executed on the JS thread.
This difference in behaviour is dangerous when we're A/B testing the TurboModule infra: One could write a NativeModule that requires main queue setup, and have it expose constants that access objects/state only accessible on the UI thread. This NativeModule would work fine in the legacy infra, which could be the case if the NativeModule author is testing locally. But once it ships to prod, it may run with the TurboModule system, and crash the application. To mitigate this risk, I'm removing this special main queue execution of `constantsToExport` from the legacy infrastructure.
## Consequences
- If a NativeModule's `constantsToExport` method accesses objects/state only accessible on the UI thread, it must do so by explicitly scheduling work on the main thread. I wrote up a codemod to fix this for our OSS modules: D21797048.
- Eagerly initialized NativeModules that required main queue setup had their constants calculated eagerly. After the changes in this diff, those NativeModules will have their constants calculated lazily. I don't think this is a big deal because only a handful of NativeModules are eagerly initialized, and eagerly initialized NativeModules are going away anyway.

This change is especially important for Fabric when a lot of objects (mostly ShadowNodes) have shared ownership. Without this change, JSVM could not know that bunch of natively allocated objects should be deallocated.
Changelog: [Internal] Fabric-specific internal change.

Summary:
## Motivation
We got this crash T67304907, which shows a `EXC_BAD_ACCESS / KERN_INVALID_ADDRESS` when calling this line:
```
NativeModulePerfLogger::getInstance().asyncMethodCallBatchPreprocessStart();
```
There are no arguments in that call, so I figured the only error could be when we try to invoke `getInstance()` or `asyncMethodCallBatchPreprocessStart()`.
This diff:
1. Removes the `NativeModulePerfLogger::getInstance()` bit. Now NativeModulePerfLogger is used via regular static C functions. So, there's no way that simply invoking one of the logging functions crashes the application: there's no vtable lookup.
2. Inside each logging function, when perf-logging is disabled, the global perflogger should be `nullptr`. This diff makes it so that in that case, we won't execute any code in the control group of the perf-logging experiment.
## Changes
**How do we enable NativeModule perf-logging?**
- Previously:
- `NativeModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`.
- Now:
- `BridgeNativeModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
**How do we do NativeModule perf-logging now?**
- Previously:
- `NativeModulePerfLogger::getInstance().command(...args)`
- `TurboModulePerfLogger::getInstance().command(...args)`.
- Now:
- `BridgeNativeModulePerfLogger::command(...args)`
- `TurboModulePerfLogger::command(...args)`.
The benefit of this approach is that each method in `BridgeNativeModulePerfLogger` is guarded with an if check. Example:
```
void moduleCreateConstructStart(const char *moduleName, int32_t id) {
NativeModulePerfLogger *logger = g_perfLogger.get();
if (logger != nullptr) {
logger->moduleCreateConstructStart(moduleName, id);
}
}
```
Therefore, we don't actually execute any code when perf-logging is disabled.

Summary:
## Motivation
This rename will fix the following CircleCI build failures:
- [test_ios_unit_frameworks](https://circleci.com/gh/facebook/react-native/150473?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link)

## Investigation
We have 4 podspec targets that map to the same header namespace (i.e: `header_dir`) `ReactCommon`:
- **New:** `React-perflogger`: Directory is `ReactCommon/preflogger`, and contains `NativeModulePerfLogger.{h,cpp}`.
- `React-runtimeexecutor`: Directory is `ReactCommon/runtimeexecutor`, and contains only `RuntimeExecutor.h`
- `React-callinvoker`: Directory is `ReactCommon/callinvoker`, and contains only `CallInvoker.h`
- `ReactCommon/turbomodule/core`: Directory is `ReactCommon/turbomodule`, and contains C++ files, as well has header files.
**The problem:**
We couldn't import headers from `React-perflogger` in `ReactCommon/turbomodule/core` files.
**The cause:**
I'm not entirely sure why, but I was able to discern the following two rules by playing around with the podspecs:
1. If your podspec target has a cpp file, it'll generate a framework when `USE_FRAMEWORKS=1`.
2. Two different frameworks cannot map to the same `module_name` or `header_dir`. (Why? No clue. But something breaks silently when this is the case).
So, this is what happened when I landed `React-perflogger` (D21443610):
1. The TurboModules code generates the `ReactCommon` framework that uses the `ReactCommon` header namespace.
2. `React-runtimeexecutor` and `React-callinvoker` also used the `ReactCommon` header namespace. However, neither generate a framework because of Rule 1.
3. When I comitted `React-perflogger`, I introduced a second framework that competed with the `ReactCommon` framework (i.e: TurboModules code) for the `ReactCommon` header namespace. Rule 2 violation.
## Thoughts on renaming
- `<perflogger/NativeModulePerfLogger.h>` is too generic, and the `perflogger` namepsace is used internally within FB.
- `<react/perflogger/NativeModulePerfLogger.h>` matches our fabric header format, but I'm pretty sure that slashes aren't allowed in `header_dir`: I tested this and it didn't work. IIRC, only alphanumeric and underscore are valid characters for `header_dir` or `module_name`. So, I opted to just use `reactperflogger`.
