Eloy Durán 941bc0ec19 Upstream RN macOS Hermes integration bits (#29748)
Summary:
Microsoft’s RN for macOS fork supports the Hermes engine nowadays https://github.com/microsoft/react-native-macos/pull/473. As a longer term work item, we’ve started moving bits that are not invasive for iOS but _are_ a maintenance burden on us—mostly when merging—upstream. Seeing as this one is a recent addition, it seemed like a good candidate to start with.

As to the actual changes, these include:

* Sharing Android’s Hermes executor with the objc side of the codebase.
* Adding a CocoaPods subspec to build the Hermes inspector source and its dependencies (`Folly/Futures`, `libevent`).
* Adding the bits to the Xcode build phase script that creates the JS bundle for release builds to compile Hermes bytecode and source-maps…
* …coincidentally it turns out that the Xcode build phase script did _not_ by default output source-maps for iOS, which is now fixed too.

All of the Hermes bits are automatically enabled, on macOS, when providing the `hermes-engine-darwin` [npm package](https://www.npmjs.com/package/hermes-engine-darwin) and enabling the Hermes pods.

## Changelog

[General] [Added] - Upstream RN macOS Hermes integration bits

Pull Request resolved: https://github.com/facebook/react-native/pull/29748

Test Plan:
Building RNTester for iOS and Android still works as before.

To test the actual changes themselves, you’ll have to use the macOS target in RNTester in the macOS fork, or create a new application from `master`:

Emilis Baliukonis 232517a574 Implement nativePerformanceNow to improve Profiler API results (#27885)
Summary:
When experimenting with React Profiler API (https://reactjs.org/docs/profiler.html), I noticed that durations are integers without a debugger, but they are doubles with higher precision when debugger is attached. After digging into React Profiler code, I found out that it's using `performance.now()` to accumulate execution times of individual units of work. Since this method does not exist in React Native, it falls back to Javascript `Date`, leading to imprecise results.

This PR introduces `global.nativePerformanceNow` function which returns precise native time, and a very basic `performance` polyfill with `now` function.

This will greatly improve React Profiler API results, which is essential for profiling and benchmark tools.

## Changelog

[General] [Added] - Implement `nativePerformanceNow` and `performance.now()`
Pull Request resolved: https://github.com/facebook/react-native/pull/27885

Test Plan:
```
const initialTime = global.performance.now();
setTimeout(() => {
  const newTime = global.performance.now();
  console.warn('duration', newTime - initialTime);
}, 1000);
```

Joe Loser ba18ee9b87 Replace folly::make_unique with std::make_unique (#26730)
Summary:
There is a mixed usage of `folly::make_unique` and `std::make_unique`. Soon, `folly::make_unique` may be removed (see [this PR](https://github.com/facebook/folly/pull/1150)). Since `react-native` only supports C++14-compilers and later, switch to always using `std::make_unique`.

## Changelog

[Internal] [Removed] - Replace folly::make_unique with std::make_unique
Pull Request resolved: https://github.com/facebook/react-native/pull/26730

Test Plan:
Running the existing test suite. No change in behavior is expected.
