We have introduced RevisionStore::newRevisionsFromBatch that is capable of creating a batch of RevisionRecord instances given the batch of database rows. Additionally, in T230834 we've introduced BlobStore::getBlobBatch to fetch a batch of blobs given the addresses. This task is about connecting the two.

RevisionStore::newRevisionsFromBatch has a content option, that indicates that the content of certain slot of all the revisions within the batch should be preloaded. Ideally if this flag is set, we don't want to use the BlobStore::getBlobsBatch for all the slots and then provide them into RevisionStore::newRevisionFromRowAndSlots. Perhaps expanding the public interface of this method wouldn't be too helpful, so an internal version of the method should be created.
