libsnapshot:snapuserd: Cut down memory usage
Use sorted std:vector instead of std:map to store
the mapping between chunk-id to COW operation.
Addtionally, use shrink_to_fit to cut down vector
capacity when COW operations are stored.
On a full OTA of 1.8G, Anon RSS usage is
reduced from 120MB to 68MB. No variance observed
when merge was in progress.
Bug: 182960300
Test: Full and Incremental OTA - verified memory usage
