This is mostly just preparation for merge-op. The existing
Extract method is updated to be usable for unlazying any type of refs
rather than just lazy blobs. The way views are created is simplified and
centralized in one location.

Refactor the interface to avoid such issues in the future.
BuildKit own mounts are stateless and not affected but

It is enhancement which allows to unpack image into containerd
snapshotter storage by `--output type=image,<.>=<.>,unpack=true`.
In order to support this feature, we needs to extend the Snapshotter
witwh `Name() string` function. Because we needs to set gc label for
snapshotter which need snapshotter name.
fix: #908
