Testing: add a small Addressable build including scenes

The TestCommon folder has reference built content that is used for testing, we are still playing "catch up" because the testing coverage is still spotty for all the different build pipelines and variations that UnityDataTool covers.

Currently there is no reference AssetBundles that are built by Addressables so testing of that case has only happened in adhoc fashion, e.g. with large projects. Its primarily Analyze that is of concern - the dump, archive and serialized-file commands are generalized enough that they are unlikely to have bugs specific to Addressables.

The "Scene" case is a particular special case and required fixing because it wasn't properly handled by Analyze (issue #81). So any reference content should include at least one AssetBundle containing scenes.

Bắt đầu trong thư mục TestCommon bằng cách xem xét nội dung tham chiếu đã được build hiện có và cách Analyze sử dụng nội dung đó. Tạo một Addressables AssetBundle nhỏ bao gồm ít nhất một scene, sau đó xác minh rằng nó thực hiện việc bao phủ của Analyze cho trường hợp scene được mô tả trong issue #81.
