Summary:
Rearranges folly_futures configuration into a static library only required for `hermes-inspector` + `folly_runtime` which merges `folly_json` and mutex-related implementations `folly_futures` was used for. As `hermes-executor-debug` is removed by `vmCleanup` configurations later, it allows to shave additional 300KB from the release APK size.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/32790
As the name says, I've added a `newArchEnabled` property that can be used to toggle the
New Architecture in the new app template. Users can use this to try the New Architecture in their
project by either:
* Set `newArchEnabled` to true inside the `gradle.properties` file
* Invoke gradle with `-PnewArchEnabled=true`
* Set an environment variable `ORG_GRADLE_PROJECT_newArchEnabled=true`
The Project property will also control if:
* ReactNative dependency should be built from source or not.
* The NDK should be enabled or not.
Please note that this requires RN 0.68.x to run properly (it won't work with 0.67 RCs) or a Nightly version of React Native.

Summary:
https://github.com/facebook/react-native/issues/31345
The issue to` android/app/src/main/res/values/styles.xml.`
In the base application theme, there is an explicitly added item
`<item name="android:textColor">#000000</item>`
This leads the `textColor` of the app to be black even though the theme is actually DayNight.
A permanent fix would be to not have this item added by default when creating a new project, as it is buggy behavior
## Changelog
[General] [removed] - line `<item name="android:textColor">#000000</item>` in this file `android/app/src/main/res/values/styles.xml `for the inital setup

Summary:
This PR adds support for the dark mode and dynamic theme changing to the default App template and to the related `NewAppScreen` components. Using `useColorScheme` hook forced me to refactor a bit main `App.js` file, but I think those changes are step in the right direction according to way in which React Native is used in larger apps, so new `Section` component has been extracted to reduce code redundancy/repetition inside `App`.
Additional color `darker` has been added to the `Colors` statics from `NewAppScreen` because `dark` was too bright for the Dark Mode backgrounds.
Also main `StoryBoard` on iOS has been updated to use theme based colors instead of static or hardcoded ones. There was also an unused, empty `Label` which I have removed.
~~I'm not so much experienced with Android. If someone could also update Android splash screen (if Android requires such change) it will be nice. I want to look at this later using simulator.~~
> I have updated the Android splash screen and tested this change on the Android emulator.
If you have any comment or corrections feel free to post them out, I would like to put more work into this PR if it's needed. Dark Mode this days is a part of near every OS, so it could be considered as a standard feature. I hope those changes helps people which struggle with the basic theming implementation (+ there is now an example of hook and `children` prop usage in the template).

Summary:
Most RN apps have single activity, and developers expect to resume application from background when app icon pressed. But Android default configuration creates a new activity instance, which confuses developers, see https://github.com/facebook/react-native/issues/27370 and https://github.com/facebook/react-native/issues/27368.
This PR changes template manifest so that when app icon pressed, background app will resume instead of creating a new activity, therefore match developers expectations. Also it's required to make Linking work.

Summary:
By default, the text color is `#000000` on iOS and different on Android, e.g. `#808080`, depending on the manufactorer.
This PR changes it so that newly created projects all have the text color `#000000` by default on both iOS and Android.
The argument for this is to make the app by default be more consistent between platforms.
Expo also does this: https://github.com/expo/expo/blob/master/android/expoview/src/main/res/values/styles.xml#L31

This PR is trying to improve Android Network Security configuration introduced in https://github.com/facebook/react-native/commit/84572c4051f11f68ddf0928d2c3df5850ae15491. I found that Android merges all manifest files into a single manifest file when building an app, so this PR provides AndroidManifest.xml with network security config in debug folder, that will be used only for debug builds. Also the network security configuration will be applied to only app that target API 28. Moved security config file to xml-v28, so that it'll only visible to API 28 and above.
