fix(storage): do not open/download blobs when validating manifests (#1566)

Browse Source 
when pushing manifests, zot will validate blobs (layers + config blob) are
present in repo, currently it opens(in case of filesystem storage) or download(
in case of cloud storage) each blob.

fixed that by adding a new method ImageStore.CheckBlobPresence() on storage
to check blobs presence without checking the cache like ImageStore.CheckBlob() method does.
