A new version of ktfmt broke the OSS CI build for React Native.
That's due to us running still on the older version of ktfmt, as the newer version hasn't been released yet.
I'm temporarly disabling the `ktfmtCheck` jobs because we primarly check formatting from within fbsource.

property from the `gradle.properties` file.
With this patch instead we hardcode the property to true, so all the libraries can consume

Summary:
This PR adds the basic `ktfmt` setup in OSS to lint Kotlin files before they're imported into the Meta codebase, making collaboration with external contributors smoother for Android related PRs.
I tried to put together certain rules that mimic the current code style and it seems to work well as I get no errors for properly formatted files but this still might need some input to have the correct configuration.
Added two scripts to the main package.json:
- To check the files format you can run: `yarn lint-kotlin-check`
- To apply formatting fixes, run: `yarn lint-kotlin`

Summary:
I've implemented a feature that automatically bundles the Metro Bundler's IP address into Android builds. This change aligns the Android development experience with iOS, allowing the app to maintain a connection to the Metro Bundler even when disconnected from USB.
Currently, in iOS builds, the IP address of the computer running the Metro Bundler is automatically bundled into the app, ensuring seamless connectivity even when the device is disconnected from USB. In contrast, Android developers must manually input the IP address if the USB connection is lost, which can be tedious and error-prone.
More info in discussion thread: https://github.com/react-native-community/discussions-and-proposals/issues/870
I anticipate that a change where making IP the default method of connection will result in a lot of people running into issues where they can't connect to Metro server (for example, if they're on a different network, or they disable wifi). So I also changed the default error message you get in case the app can't connect to the bundler and updated the "Change Bundle Location" dev menu.
The previous error message
```
Unable to load script. Make sure you're either
running Metro (run 'npx react-native start') or
that your bundle 'RNTesterApp.android.bundle' is
packaged correctly for release.
```
was changed to:
```
Unable to load script.
Make sure you're running Metro (npx react-native start)
or that your bundle 'RNTesterApp.android.bundle' is
packaged correctly for release.
The device must be on the same WiFi as your laptop to
connect to Metro.
To use USB instead, shake the device to open the dev
menu and set the bundler location to 'localhost: 8081'
and run:
adb reverse tcp:8081 tcp:8081
```
And the new dev menu UI looks like this:
The two buttons with "10.0.2.2:8081" and "localhost:8081" are suggestions which when tapped fill the input with the text from the button. The first button suggests the IP of the development machine, and the second one is hardcoded to localhost:8081.
## Changelog:
[ANDROID] [CHANGED] - Automatically use Metro bundler IP address when installing apps on Android
Pull Request resolved: https://github.com/facebook/react-native/pull/49166
Test Plan:
I've tested the implementation on a physical device and on emulator and it's working solid. However, I would invite further testing in order to catch possible edge cases.
I've recorded common scenarios
Scenario 1:
Device doesn't have the app installed.
We connect the device via USB, install the app and open it.
Device is on the same network as the dev machine.
Bundler location is by default set to the IP of the dev machine.
When starting app, the app is able to connect to the dev machine and download the bundle.
Scenario 2:
Device doesn't have the app installed.
Wi-Fi is turned off on the device but device is connected via USB
We install the app and open it.
Bundler location is by default set to the IP of the dev machine.
When starting app, the app is not able to connect to the dev machine and shows the error message.
After opening the dev menu we see that the IP is set to the IP of the dev machine.
We click the "localhost" option in the dev menu and click apply
After that the app is able to connect to the dev machine and download the bundle (via USB) since the traffic is forwarded using adb reverse.
Notes:
When we set an IP in the dev menu, the app will persist it.
If we connect the device via USB and reinstall the app the persisted data stays the same, so the previously set IP will be used.
However, the IP of the dev machine will be displayed as an option in the dev menu.

This diff introduces a new property called `legacyWarningsEnabled` for `gradle.properties` that
toggles the Legacy Arch warnings for users.
I've also introduced a new `ReactNativeApplicationEntryPoint` that is generated by RNGP. This class
effectively wrap `DefaultNewArchitectureEntryPoint` by setting warnings and also invoking SoLoader.
It will reduce the errors in the user space.
As of now warnigns appear in Logcat, but I'm looking into adding some UI in a subsequent diff.
