• Updated CMakeLists.txt files (root, app, release_build_files) to remove references to dynamic_links and invites.
• Updated Gradle build files (Android/firebase_dependencies.gradle, release_build_files/Android/firebase_dependencies.gradle, settings.gradle) to remove dynamic_links and invites dependencies and resource references.
• Updated build scripts (build_scripts/ios/build.sh, build_scripts/packaging.conf) to remove dynamic_links.
• Updated GitHub Actions workflows (.github/workflows/cpp-packaging.yml, .github/workflows/integration_tests.yml) to remove dynamic_links.

Next steps involve removing test configurations and documentation related to Dynamic Links and Invites.
