topic: preliminary refactoring in the restore tool code

[jepett0]

Preliminary refactoring so that the future addition of the BackupTopic function would have less diffs with the main branch.

Added SerializeTo and DeserializeFrom (in a form of a constructor) for some of the structures used in topic SDK. This way we would able to call CreateTopic on restore (see in the next PR) with TCreateTopicSettings built from the Ydb::Topic::CreateTopicRequest directly.
