YT-20044: Remote copy for dynamic tables with hunk chunks
Support remote copy for dynamic table with hunk chunks.
- Still doesn't work for tables with compression dictionaries.
- Still doesn't work for tables with erasure encoded hunks, mainly due to unsupported remote copy for tables with striped erasure.
Remote copy scheme:
* fetch hunk chunk specs (same as for regular chunks);
* remote copy hunk chunks (TRemoteCopyHunkTask), each job returns HunkChunkIdMapping (old -\> new);
* add HunkChunkIdMapping to remote copy spec to patch chunk meta;
* remote copy chunks (TRemoteCopyTask);
* get hunk chunk list ids for output table;
* attach hunks to chunk lists in which tablets they are used.
Throw an error if the table has compression dictionary config in `@mount_config`.
Throw an error if a static table somehow has a non-empty HunkChunks list.
