// This function is responsible for providing all the subscenes to the build.
//
// The way these files get generated is that we have a SceneWithBuildConfiguration file, (which is a bit of a hack to work around the inability for scriptable importers to take arguments, so
// instead we create a different file that points to the scene we want to import, and points to the buildconfiguration we want to import it for). The SubsceneImporter will import this file,
// and it will make 3 (relevant) kind of files:
// - headerfile
// - entitybinaryformat file (the actual entities payloads)
// - a SerializedFile that has an array of UnityEngine.Object PPtrs that are used by this entity file.
//
// The first two we deal with very simply: they just need to be copied into the build, and we're done.
// the third one, we will feed as input to the Scriptable build pipeline (which is actually about creating assetbundles), and create an assetbundle that
// has all those objects in it that the 3rd file referred to. We do this with a batch api, first we loop through all subscenes, and register with this batch
// api which assetbundles we'd like to see produced, and then at the end, we say "okay make them please". this assetbundle creation api has a caching system
// that is separate from the assetpipeline caching system, so if all goes well, the call to produce these assetbundles will return very fast and did nothing.
//
// The reason for the strange looking api, where a two callbacks get passed in is to make integration of the new incremental buildpipeline easier, as this code
// needs to be compatible both with the current buildpipeline in the dots-repo, as well as with the incremental buildpipeline. When that is merged, we can simplify this.
