Xiang Wei c65ec3136b [Improvement] spark load without agg and de/serialization (#6270) ...

fix #6269 

The outline of our changes is to improve our memory in case of OOM in BE and to speed up the calculation.
1. We do not need to do Aggregation in load, which has already been done in the ETL spark job.
2. Based on 1, we do not need to serialize/deserialize bitmap/HLL objects.
