    phase1: fix CONFIG_SIGNED_PACKAGES for apk signing
    
    Currently `CONFIG_SIGNED_PACKAGES` is only enabled when `usign_key` is
    configured. However, we also want to enable it when `apk_key` is
    configured, as we support signing APK packages as well.
    
    So lets fix it by adding `IsSignedPackagesEnabled` helper which checks
    for both keys and updates the .config generation to use it.
