/// Convert the Asset path to the asset path required for loading.
/// For example, if the loader wants to load resources under the Resources path, then the returned path should be the file path under Resources, excluding the extension.
/// If the loader is to load AssetBundle, then the path where the resource is located may be StreamingAssets or a custom path, then it is up to the user to generate the path he needs according to the actual situation.
