Lion - dapplion 812913643b Range sync: fetch data columns via custody-by-root (#9496) ...

- Generalize the custody-by-root request to accept a `Vec<Hash256>` of block roots so a whole batch is fetched in one request; `DataColumnsByRootRequestParams { block_roots, indices }` completes at `block_roots.len() * indices.len()`.
- `custody_lookup_request` takes `block_roots: &[Hash256]` + `block_epoch`; `cached_data_column_indexes` takes `block_epoch`.
- `block_sidecar_coupling.rs`: couple a batch's blocks with the columns returned by the single custody-by-root request; drop the per-column request map and retry/faulty-peer machinery.
- Remove the now-unused columns-by-range range-sync path and the serialize-downloads gate.
