Migrate ReactClippingViewGroupHelper.java to Kotlin

[Priyanka26012]

Summary:

Migrated ReactClippingViewGroupHelper.java to Kotlin as part of the React Native Kotlin migration initiative.
This change helps modernize the React Native Android codebase and improve maintainability.
No functional changes were introduced—only a language conversion while preserving the original logic and behavior.

Changelog:

[ANDROID] [CHANGED] - Migrated ReactClippingViewGroupHelper.java to Kotlin

Test Plan:

✅ Ran yarn && yarn android in the root directory and verified RNTester builds successfully.
✅ Opened RNTester on an Android emulator/device and navigated through various screens to ensure the app works as expected.
✅ Specifically tested views with removeClippedSubviews enabled to confirm runtime behavior remains unchanged.
✅ Used KtFmt to format the Kotlin file properly.
