Since the goal of this pull request is to migrate the example apps to built-in Kotlin and the new DSL, these flags should be set to true. Setting them to false disables the built-in Kotlin support.

Furthermore, because kotlin-android was removed from build.gradle.kts, having android.builtInKotlin=false will cause Gradle to fail with an error like Extension with name 'kotlin' does not exist because the Kotlin plugin is never applied.

Please update this flag to true across all gradle.properties files in this PR.
