Add performance track for React Native renderer (#56003)

Changelog: [General][Added] Add new custom track for React Native Renderer operations in React Native DevTools performance traces

This diff adds performance tracking instrumentation to the React Native renderer to provide visibility into rendering operations in React Native Developer Tools traces.

On Android (Kotlin), the `MountItemDispatcher` is updated to wrap key mounting operations (view commands, premount, and mount) with `PerformanceTracer.trace` calls. These traces appear on the "Renderer" track within the "⚛ Native" track group.

On C++ (shared renderer), the `ShadowTree::tryCommit` method is instrumented with `PerformanceTracerSection` to track commit and layout operations. The commit trace includes metadata about the source of the commit (e.g., React).

This is a reland of a previously reverted change.
