The `marchingFallback` directive is applied directly on the build type.
However here is invoked inside the `externalNativeBuild` making it confusing, because in reality
it has nothing to do with `externalNativeBuild`. So I'm moving it to the correct location
(this has no effect on the build setup, is just to make the code easier to read).

I've been looking into the next major bump of AGP to 9:
https://developer.android.com/build/releases/agp-preview#android-gradle-plugin-built-in-kotlin
This change adapts our project so that it keeps on buildign with AGP 8
(as the bump to 9 would be a breaking change), but it addresses some of the build
failures we'll be having with AGP 9:
- Set `resValues` build option to true (default was changed true -> false in AGP 9)
- Opts out our project from `android.builtInKotlin` and `android.newDsl` for the time being.

I've just realized we ended up invoking `project.` inside the execution of `BundleHermesCTask`.
This is an anti-pattern and is breaking Gradle Configuration caching.
Instead we should be checking if hermesV1Enabled is set during the Task registration and pass over this information
to the task.

Adds a new `version.properties` file to keep which hermes versions should be consumed from Maven once the versions of Hermes and React Native are decoupled. This diff only implements changes necessary for consuming Hermes V1, as we don't want to migrate everything quite yet (0.82).

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.

This creates a `debugOptimized` build type for React Native Android, meaning that we can run C++ optimization on the debug build, while still having the debugger enabled. This is aimed at improving the developer experience for folks developing on low-end devices or emulators.
Users that intend to debug can still use the `debug` variant where the full debug symbols are shipped.

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`
## Changelog:
[INTERNAL] - Kotlin: Set up ktfmt in OSS

```diff

Summary:
This follows https://github.com/facebook/react-native/pull/47554
Compared to the initial proposal, I had to remove the `edgeToEdgeEnabled` property from the root `gradle.properties` and put it in the app `gradle.properties` instead (explaining the `AgpConfiguratorUtils.kt` / `GenerateEntryPointTask.kt` / `ProjectUtils.kt` / `PropertyUtils.kt` changes)
This PR:
- Enable edge-to-edge for `MainActivity` (when `edgeToEdgeEnabled` is set to `true`)
- Disable `StatusBar` `backgroundColor` and `translucent` (when `edgeToEdgeEnabled` is set to `true`)
- Enforce `statusBarTranslucent` and `navigationBarTranslucent` on `Modal` when edge-to-edge is enabled
- Add an `isEdgeToEdge` constant to `DeviceInfoModule` for [`react-native-is-edge-to-edge`](https://github.com/zoontek/react-native-edge-to-edge/tree/main/react-native-is-edge-to-edge) detection
