Changelog: [internal]
This adds a new environment variable to Fantom that allows debugging the JS code in tests.
Usage:
```
FANTOM_DEBUG_JS=1 yarn fantom <test>
```
**Does NOT work in OSS yet**. We need to include a third-party library to send HTTP and WebSocket requests and implement a wrapper on top of it.

## Changelog:
[Internal] [Changed] - Cache result when RenderOutput::render() is called
Rreviously, root.getRenderedOutput in fantom doesn't really reflect the result of direct manipulation from native animated (see the test case added here). This stack is enabling it.
* make RenderOutput an instance owned by TestMountingManager that can cache render result
* why is this needed - native animation's direct manipulation should modify the render result (analog to directly manipulating host views on a platform) instead of props on a StubView
* here i also make sure that `RenderOutput::render()` will only re calculate the render result for a tree after StubViewTree::mutate is called

Changelog: [internal]
This adds **support for creating Hermes/JS sampling profiler traces in Fantom**, which is especially useful when running benchmarks.
Usage:
```
FANTOM_PROFILE_JS=1 yarn fantom Animated-benchmark
```
Output:
{F1980642216}
After this, the trace is fully symbolicated.
Can be opened directly in Google Chrome:
{F1980642229}
Or in the built-in viewer in VSCode:
{F1980642242} {F1980642240} {F1980642241}
When collapsing frames in the Flame Chart viewer in VSCode, we can quickly identify opportunities for optimizations.
This also supports multi-config environments. In that case, trace file names are created using a short representation of the configuration.
User guide for benchmarks in Fantom, including how to use this, will be done in a future diff.
NOTE: This still doesn't work in OSS because we don't support optimized mode there. In dev mode, there's a segmentation fault coming from this line: `hermesRuntime->sampledTraceToStreamInDevToolsFormat(fileStream)`

Pull Request resolved: https://github.com/facebook/react-native/pull/52839
**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`).

OSS build is broken atm as there is rn-tester dep in Fantom, needed for Meta only purposes.
Platformizing code to allow for Meta only implementation here and also for OSS only. Using this approach over ifdef.

## Changelog:
[General][Deprecated] - ShadowNode::Shared is now deprecated. Use `std::shared_ptr<const ShadowNode>` instead.
- Mark ShadowNode::Shared as deprecated in ShadowNode.h
- Replace all uses of ShadowNode::Shared with std::shared_ptr<const ShadowNode>.
This continues the systematic effort to remove ShadowNode type aliases in favor of explicit standard library types for improved code clarity and maintainability.
