Pull Request resolved: https://github.com/facebook/react-native/pull/45473
This is a basic implementation of the Long Tasks API (https://w3c.github.io/longtasks/).
It detects and reports long tasks when using the Event Loop (in the modern RuntimeScheduler) when a new feature flag for this purpose is enabled.
This doesn't include attribution information at the moment.

These APIs are not currently enabled in OSS, so moving the modules should be safe and not considered a breaking change.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42762
This renames `performance.reactNativeStartupTiming` as `performance.rnStartupTiming` to align with the recommended vendor prefix for React Native.
This API is still private, so it's safe to rename.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/38323
This change makes the returned values from `performance.reactNativeStartupTiming` to accept null or undefined. This is done as some platforms may not have certain startup timing information, and as a default value, it's discussed that null/undefined is better than zero.
- Use `unorderedMap` instead of custom timing object for the C++ native module return value
- Use `std::nan` as initialized value for unset doubles
- Update examples to reflect the latest changes

This diff adds the two extra markers `initializeRuntimeStart` and `initializeRuntimeEnd` to the startup performance API. The runtime start time matches the existing android marker `GET_REACT_INSTANCE_MANAGER_START`, which is the first marker we have on the RN android app.

Summary:
Right now RNTestePage either adds a large spacer to the end of content, unless `noSpacer` is added. But with `noSpacer`, scrolling content may not be reachable because we are putting padding on the wrong container.
This fixes that and removes a few cases where we had multi hundred px empty space in favor of uniformly taking up the parent, and a 10px padding. This also moves the constant margin at the top of RNTesterBlock to the container, so that in the E2E container we can save the 30px.

Summary:
Recent integration from Windows brought in PerformanceApiExample that uses relative pathing to access react-native library. This causes us to have to override the file since our file structure is different. https://github.com/microsoft/react-native-windows/issues/11373
This PR changes the example to use module pathing instead.

Summary:
This diff adds the `performance.reactNativeStartupTiming` API to the performance global object for RN. This property does not exist in web, and we are free to make up our own list of properties in the startup metrics to track RN app startup process. In our case, we have the following six properties to begin with (we may extend and add more to this list in the future):
```
- `(start|end)Time`: The time ‘zero’ for the startup timing and the end of app startup. RN has no knowledge of app start time, which will be provided by the platform. The `endTime` will be the time when the first JS bundle finishes executing (Note that RN supports multiple JS bundles, which can be loaded async)
- `executeJavaScriptBundleEntryPoint(Start|End)`: The time for RN to execute the JS entry point (and finish all sync job)
```
