Support for Play Asset Delivery

It would be great if microG support Play Asset Delivery, allowing games to download assets from Play Store server. Without the support, the games can't download assets. More info: https://developer.android.com/guide/playcore/asset-delivery

Start with the Play Asset Delivery documentation linked in the issue and the logged service intent, com.google.android.play.core.assetmoduleservice.BIND_ASSET_MODULE_SERVICE. Use the listed games and provided logs to investigate the missing service binding; done means Play Asset Delivery requests no longer fail with that error and the games can download their assets.
