enhance: Remove bf from datanode (#36367) (#37027)
Remove bf from datanode:
1. When watching vchannels, skip loading **flushed** segments's bf. For
generating merged bf, we need to keep loading **growing** segments's bf.
2. Bypass bloom filter checks for delete messages, directly writing to
L0 segments.
3. In version 2.4, when dropping a partition, marking segments as
dropped depends on having the full segment list in the DataNode. So, we
need to keep syncing the segments every 10 minutes.
