Today each time there's shards to snapshot we enqueue a lambda which captures the current `SnapshotsInProgress$Entry`. This is a pretty heavyweight object, possibly several MB in size, most of which is not necessary to capture, and with concurrent snapshots across thousands of shards we may enqueue many hundreds of slightly different such objects. With this commit we compute a more efficient representation of the work to be done by each task in the queue instead. Relates elastic#77466 Backport of elastic#88707
