export (or don't) all activities, activity aliases, services, and broadcast receivers with intent filters

Uploading a signed sdk 31 bundle to play store fails:

You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set. This file can't be installed on Android 12 or higher. See: developer.android.com/about/versions/12/behavior-changes-12#exported
