[server][dvc] transfer offsetRecord and storeVersionState during blob transfer

Transfer offsetRecord and storeVersionState during blob transfer

Main code changes:

1. For P2PFileTransferClientHandler:
   • No longer use inputStream to determine if the transfer is complete. Instead, use BlobTransferPartitionMetadata, which is also needed for updating the offsetRecord later.
   • For the responses, distinguish between file and metadata types. If it's a file type, write the file; if it's a metadata type, use it to update the metadata.
   • In bootstrapFromBlobs, once the metadata is transferred, update the offsetRecord in storageMetadataService and update the SVS via StoreVersionStateSyncer.
2. For P2PFileTransferServerHandler:
   • After P2PFileTransferServerHandler sends the file and before sending the BLOB_TRANSFER_COMPLETED flag, the server handler sends metadata record information with the partition's latest offset and store version state, retrieved from StorageMetadataService.

Minor code change:

• Move the blob transfer client/server from venice-common to davinci, because it will use storageMetadataService to get the necessary offset/SVS information. Otherwise, it will cause a cyclic dependency.
