Use `OnApplyWindowInsetsListener` to get window insets.

EdgeToEdgeActivity.kt

class EdgeToEdgeActivity : ViewBindingActivity<ActivityMainBinding>() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setupWindow()
    }
    
    private fun setupWindow() {
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(binding.root) { v, insets ->
            TODO("Handle window insets here.")
        }
    }
}
