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.
## Changelog
[General] [Added] - Upstream RN macOS Hermes integration bits
Pull Request resolved: https://github.com/facebook/react-native/pull/29748
Test Plan:
Building RNTester for iOS and Android still works as before.
To test the actual changes themselves, you’ll have to use the macOS target in RNTester in the macOS fork, or create a new application from `master`:

This rename will fix the following CircleCI build failures:

## 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`.

Summary:
This diff instruments two markers:
- JSRequireBeginning: From the start of the JS require to when we start creating the platform NativeModule
- JSRequireEnding: From the end of platform NativeModule create to the end of the JS require
In order to accomplish this, I had modify `ModuleRegistry::ModuleRegistry()` to accept a `std::shared_ptr<NativeModulePerfLogger>`. I also had to implement the public method `ModuleRegistry::getNativeModulePerfLogger()` so that `JSINativeModules` could start logging the JS require beginning and ending.

Summary:
## Context
For now, assume TurboModules doesn't exist.
**What happens when we call an async NativeModule method?**
Everytime JS calls an async NativeModule method, we don't immediately execute it. The legacy infra pushes the call into some queue managed by `MessageQueue.js`. This queue is "flushed" or "emptied" by the following events:
- **Flushed:** A C++ -> JS call. NativeModule async methods can called with an `onSuccess` and/or `onFail` callback(s). Calling `NativeToJsBridge::invokeCallback` to invoke one of these callbacks is one way for ObjC++/C++/Java to call into JS. Another way is via JSModule method calls, which are initiated by `NativeToJsBridge::callFunction`.
- **Flushed:** When `JSIExecutor::flush` is called. Since TurboModules don't exist, this only happens when we call `JSIExecutor::loadApplicationScript`.
- **Emptied:** When more than 5 ms have passed, and the queue hasn't been flushed/emptied, on the next async NativeModule method call, we add to the queue. Afterwards, we empty it, and invoke all the NativeModule method calls.
**So, what's the difference between flushed and emptied?**
> Note: These are two terms I just made up, but the distinction is important.
If the queue was "flushed", and it contained at least one NativeModule method call, `JsToNativeBridge` dispatches the `onBatchComplete` event. On Android, the UIManager module is the only module that listens to this event. This `onBatchComplete` event doesn't fire if the queue was "emptied".
**Why does any of this matter?**
1. TurboModules exist.
2. We need the TurboModules infra to have `JsToNativeBridge` dispatch `onBatchComplete`, which depends on:
- **Problem 1:** The queue being flushed on calls into JS from Java/C++/ObjC++.
- **Problem 2:** There being queued up NativeModule async method calls when the queue is flushed.
In D14656466, fkgozali fixed Problem 1 by making every C++/Java/Obj -> JS call from TurboModules also execute `JSIExecutor::flush()`. This means that, with TurboModules, we flush the NativeModule async method call queue as often as we do without TurboModules. So far, so good. However, we still have one big problem: As we convert more NativeModules to TurboModules, the average size of the queue of NativeModule method calls will become smaller and smaller, because more NativeModule method calls will be TurboModule method calls. This queue will more often be empty than not. Therefore, we'll end up dispatching the `onBatchComplete` event less often with TurboModules enabled. So, somehow, when we're about to flush the NativeModule method call queue, we need `JsToNativeBridge` to understand that we've executed TurboModule method calls in the batch. These calls would have normally been queued, which would have led the queue size to be non-zero. So if, during a batch, some TurboModule async method calls were executed, `JsToNativeBridge` should dispatch `onBatchComplete`.
**So, what does this diff do?**
1. Make `Instance` responsible for creating the JS `CallInvoker`.
2. Make `NativeToJsBridge` responsible for creating the native `CallInvoker`. `Instance` calls into `NativeToJsBridge` to get the native `CallInvoker`.
3. Hook up `CatalystInstanceImpl`, the Android bridge, with the new JS `CallInvoker`, and the new native `CallInvoker`. This fixes `onBatchComplete` on Android. iOS work is pending.

Summary:
This diff includes a few changes:
1. Move the headers inside `jsiexecutor` into `jsiexecutor/jsireact`. As far as I'm aware, the Android ndk build system isn't flexible enough to support header namespaces, so we can't just expose the headers inside the `jsiexecutor` directory under the `jsireact` namespace. Therefore, I moved the headers to `jsiexecutor/jsireact`, and added `jsiexecutor` to the header search path. This was the easiest way to simulate `jsireact` namespace.
2. Setup the Android.mk files to get RNTester compiling and running.
3. Introduce a `jscexecutor` module to make `JSCExecutor.java` execute without throwing.
**Note:** Moving the header files inside `jsiexecutor` probably breaks the iOS builds and internal builds. I'll fix those in subsequent diffs on this stack.

Summary:
Adds C++ delta client that keeps modules in memory, and can be used as a RAM bundle.
For now, this client expects a `folly::dynamic` object as payload for patches, i.e. the JSON response retrieved from Metro needs to be parsed with `folly::parseJson` by the caller.
In the future, we will replace JSON with a streaming friendly binary format.
