Alex HuntandFacebook GitHub Bot a3bf989450 Implement reporting InteractionEntry live metrics to runtime (#52839)
Summary:
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`).
