### Motivation In some cases cursor position info can be too large to serialize as a single entry, e.g. in case of too many deleted ranges. Also the serialization can be too slow. cherry-picks of changes by @eolivelli @nicoloboschi and I. ### Modifications Cursor PositionInfo serialization is reworked to produce less garbage/serialize faster; serialized data can be compressed. In case the serialized data too large it is chunked and saved as a sequence of entries. ### Verifying this change - [ ] Make sure that the change passes the CI checks.
