fix: Clone child segment info before decompress its deltalog (#31792 )

Related to #31791

This segment meta is implemented in COW pattern. All modification on
segment info shall happen on the copied version of it.

This PR clones the child segment info for `GetSegmentInfo` in case data
race problem.

Data Coordinator

Data cooridnator(datacoord for short) is the component to organize DataNodes and segments allocations.

Dependency

KV store: a kv store has all the meta info datacoord needs to operate. (etcd)
Message stream: a message stream to communicate statistics information with data nodes. (Pulsar)
Root Coordinator: timestamp, id and meta source.
Data Node(s): could be an instance or a cluster, actual worker group handles data modification operations.
