Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52838
**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**
Wires up a client/subscriber for the `"__chromium_devtools_metrics_reporter"` runtime binding (to which we emit live metrics events since D78904748). This will be used to unpack these performance updates to send to the host platform.
- Creates a new `HostRuntimeBinding` helper, which establishes a local/private CDP session.
- Conditionally installs our perf metrics runtime binding in `HostTarget` when `perfMonitorV2Enabled` is set.
- Wires up a new `onPerfMonitorUpdate` event on `HostTargetDelegate` (unimplemented until the next diff).

Summary:
The `aria-label` prop was ignored on `TextInput` component. Which resulted in screen reader not able to read it.
This PR forwards `aria-label` to `accessibilityLabel` in a manner similar to e.g. `View` and `Text`

We never call `stopTracing()` on a HostTarget, if the Agent was destroyed.

Now TraceRecordingState should capture everything we need in order to display a trace on a timeline.

We would need this to correctly serialize Runtime Sampling Profiles.
In case of recording the trace in the background, this might not be the value we would want to use, we would probably add another field or calculate it dynamically, depending on the tracing mode.
This is not the case for now, will be solved separately on top of the stack.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52963
# Changelog: [Internal]
We are deprecating previous `InstanceTarcingProfile` struct, but not removing yet, since this is still used and we will migrate in one of the diffs at the top of the stack.
The `InstanceTracingProfile` will consist only of Trace Events that were captured by PerformanceTracer, and will not store Runtime Sampling Profiles.
There are multiple reasons for this:
1. As of right now, Runtime Sampling Profiles are completely independant from Instance Profiles and do not require anythings from Instance as a Target to be represented on a timeline.
2. Although PerformanceTracer is a singleton, it should be this way. It captures events for something that can only be dispatched if there is an allocated React Instance, so in the future PerformanceTracer could become a data-member of InstanceTarget.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52966
# Changelog: [Internal]
The current design for Tracing is flawed. Right now the logic is mostly scattered around CDP Agents, lifetime of which is tied to CDP session.
This diff introduces a new approach:
- The HostTarget will be the only Target that has public entrypoints to startTracing as part of the jsinspector backend.
- It will create and own TraceRecording that acts as a local session. We won't use wording session here, because it is already reserved for CDP case.
- Every Target will implement TracingAgent, lifetime of which will be limited by lifetime of either Target or TraceRecording.
- All these TracingAgent will have a reference to TraceRecordingState, which they can mutate
This approach unblocks:
- Recording traces without active CDP sessions, for example in a background.
- Recording full instance reloads and multiple profiles for Instances and Runtimes.

This adds a Fantom test to ensure that `setUpDefaultReactNativeEnvironment` doesn't read any feature flags. This prevents catching this as a runtime issue when the feature flag system complains that feature flags were accessed before being overridden, which always would happen if this module read any flags (as it runs before any product code that sets overrides).

This change prevents users from opting out of the New Architecure.
The change is non breaking with respect to building an app: all the functions are still there, even if they are unreachable, in case users will still call them explicitly.
We hardcoded all the values to enable the New Architecture, so there is no way to disable it.
This is a behavioral breaking change, though.

We eagerly require `AppRegistry` from environment initialization (`InitializeCore`) because it has some side-effects that are necessary for error reporting (see https://github.com/facebook/react-native/issues/34649 and https://github.com/facebook/react-native/pull/34650), but this change makes a lot of modules to be eagerly initialized.
This reduces that to avoid loading modules that not necessary for environment setup, which allows us to do things like setting up feature flags before modules like `View` and `Text` have been initialized.
