Ruslan Lesiutin f1e5c84ea7 Remove methods for capturing Processes and Threads (#52914) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52914

# Changelog: [Internal]

We can't rely on RuntimeExecutor to actually tell us what JavaScript thread number is. Although this would work correct in most of the cases, this is not the solution we should go with.

Instead, we should fetch a map <id, name> of threads from the Host. This is what we will lazily call at the start of the Trace. I will add later on top of the stack.

Devan Buggay 15373218ec Add granular control with pragma modes (#52894) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52894

Adds the following boolean pragma modes for more granular control:

```
fantom_native_opt true|false
fantom_js_opt true|false
fantom_js_bytecode true|false
```

Previously these were all set together with `fantom_mode`. These modes are mutually exclusive with `fantom_mode`.

Devan Buggay 807f0b6882 Isolate NativeDevSettings load (#52821) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52821

Hardens RN to running in mismatched opt/dev modes.

While adding an opt native/dev js mode to fantom, LogBox was trying to load NativeDevSettings when it didn't exist because of mode mismatch.

This is the only location it's happening, so this just moves the NativeDevSettings load into the one function that needs it.

**Context**

Experimental V2 Performance Monitor prototype, beginning by bringing the [Interaction to Next Paint (INP)](https://web.dev/articles/inp) metric to React Native.

**This diff**

Adds and configures a `CdpMetricsReporter` class to report `InteractionEntry` live metrics over CDP via the `"__chromium_devtools_metrics_reporter"` runtime binding.

**Notes**

- Introduces a new `react/performance/cdpmetrics` package, and a listener API on `PerformanceEntryReporter` (both to avoid a `jni` dependency in `react/performance/timeline`).

Samuel Susla 4614a0bc17 move fabric sync in C++ Animated to JS thread (#52904) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52904

changelog: [internal]

There is a race condition in `FabricUIManagerBinding::schedulerDidFinishTransaction`. Until it is addressed properly, let's do synchronisation Fabric commits through JavaScript thread.

It can have pretty serious consequences: a crash in better case and undefined behaviour in worse case.

The race is between acquiring two mutexes:
1. One inside of `MountingCoordinator::pullTransaction`
2. Second one inside of `FabricMountingManager::executeMount`

The logic inside of `FabricUIManagerBinding::schedulerDidFinishTransaction` depends on the fact that whichever thread acquires mutex number 1, will acquire mutex number 2 without interruption. But that is not always the case as threads may be interrupted.

- on-headers

This change fixes these vulnerabilities.
For the on-headers vulnerabilitiy specifically, it comes from the following dependency chain:
- rn-tester > react-native-community/cli > compression > on-headers.

To fix it, we have to force the resolution to both on-headers and compression.

Danny Su fb0e4ee6d1 Enable regenerator for Hermes dev mode transform profile (#52651) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52651

Changelog: [Internal]

Last year the `hermes-canary` profile was used to enable certain apps to use Static Hermes by enabling regenerator because debugger support for generator wasn't finished yet. However, we actually could have just keyed off of `options.dev` and still kept using `hermes-stable`.

The `hermes-canary` profile is actually meant to be used to run experiments. We should free up this profile to return it to the original intended purpose.

This diff makes all hermes profiles' dev mode use regenerator. Existing SH apps using `hermes-canary` should be unaffected. And apps using Hermes will change to use regenerator in dev mode, but that should be ok.

Ruslan Lesiutin 253249611c Extract serializers for ProfileChunk (#52870) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52870

# Changelog: [Internal]

Defines a set of static serializers for parts of the "Profile" and "ProfileChunk" Trace Events.

Mainly for 2 reasons:
1. To follow the same pattern of static serializers for Tracing.
2. To save on string copying, since ProfileChunk could contain hundreds of unique frames, all of them could have unique function names. The previous approach would copy the strings and populate a new `folly::dynamic` object.

Ruslan Lesiutin 7488097872 Extract TraceEvent serialization logic (#52869) 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52869

# Changelog: [Internal]

We are exctracting a logic for serialization of TraceEvent into a dedicated serializer class.

Conceptually:
- PerformanceTracer would be a local TraceEvent engine that is responsible for constructing and buffering TraceEvents.
- TraceEventSerializer will have a single responsibility: transforming from local structs to serialized json objects that are ready to be dispatched over CDP Tracing domain.

This would help avoid scenarios, where we are passing around `folly:dynamic` between internal subsystems: serialization should only happen right before emtting a CDP message.

# Changelog: [Internal]

- Callback that emits `Tracing.dataCollected` events will receive chunks as rvalues refs (`&&`), instead of `const &`.
- The RuntimeSamplingProfile will be passed to the serializer as rvalue ref.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52863

Changelog: [internal]

We're seeing some issues in stress runs for Fantom tests in optimized mode, failing when compiling the bytecode with Hermes. The specific error in the Hermes compiler isn't clear, but this started failing when we changed the folders for output. It's possible that it's due to race conditions in stress runs, where multiple workers are attempting to compile in the same locations.

This forces every output in every runner to be in a different file to prevent these possible collisions.
