`Allocator.Alloc` and `Allocator.AllocOne` might be invoked multiple
times if there were multiple blobs set in one sync task.
This PR add pre-fetch logic for all blobs and cache logIDs in sync task
so that at most only one call of the allocator is needed.

Fix logic problem introduced by #29413, which is serializer tries to
merge statslog list while level segments do not have statslog. This
shall result returning error. `writeBufferBase` ignores this error but
it shall only ignore `ErrSegmentNotFound`.
This PR add logic checking segment level before execution of merging
statslog list. And add error type check for getSyncTask failure.

Compacted segment info shall be removed after all buffer belongs to it
is sync-ed.
This PR add the cleanup function after triggerSyncTask logic:
- The buffer is stable and protected by mutex
- Cleanup fetches compacted & non-sync segment
- Remove segment info only there is no buffered maintained in manager
