Krzysztof Magiera b44fe4deee Provide timestamp as argument to rAF callbacks when running Jest tests (#35919)
Summary:
This change aligns requestAnimationFrame implementation used in Jest environment with web standard, and with the implementation that runs in the application environment.

As per specification https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame#parameters – requestAnimationFrame callback gets a single parameter, which represents the current frame timestamp. The current polyfill maps requestAnimationFrame directly to setTimeout which makes the callback execute without any parameters.

## Changelog

[General] [Fixed] - Jest mocked requestAnimationFrame callbacks now receive a timestamp parameter

Pull Request resolved: https://github.com/facebook/react-native/pull/35919

Test Plan:
1. execute jest test suite to make sure nothing breaks
2. add the below code to one of the tests:
```
jest.useFakeTimers();
requestAnimationFrame((timestamp) => console.log("rAF", timestamp));
jest.runOnlyPendingTimers();
jest.useRealTimers();
```
this code will print `undefined` before and numer `0` representing the mocked frame time after this change.
