enhance: reduce SyncTask AllocID call and refine code (#29701)
See also #27675

`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.
