chore(ci): optimize android app build with RN App

[hurali97]

Summary

This reduces the total time of the CI for:

• RN Tester: by ~4 minutes
• RN App + Android App: by ~5 minutes

This is mainly achieved by building only one architecture(arm64-v8a) instead of four. Apart from it, we change to gradle/actions/setup-gradle@v4 for better cache handling.

Pull request overview

This pull request optimizes CI build times by reducing the number of Android architectures built from four (armeabi-v7a, arm64-v8a, x86, x86_64) to one (arm64-v8a), and modernizes Gradle caching by switching from manual cache configuration to the official gradle/actions/setup-gradle action. These changes reduce RN Tester CI time by ~4 minutes and RN App + Android App CI time by ~5 minutes.

Changes:

• Configure single architecture (arm64-v8a) in gradle.properties for TesterIntegrated and RNApp
• Add ndk.abiFilters to AndroidApp build configuration to enforce single architecture
• Replace manual Gradle cache restoration with gradle/actions/setup-gradle@v4 in CI workflow
