LUCENE-9324: Add an ID to SegmentCommitInfo (#1434)
We already have IDs in SegmentInfo, as well as on SegmentInfos which are useful
to uniquely identify segments and entire commits. Having IDs on
SegmentCommitInfo is be useful too in order to compare commits for equality and
make snapshots incremental on generational files. This change adds a unique ID
to SegmentCommitInfo starting from Lucene 8.6. Older segments won't have an ID
until the segment receives an update or a delete even if they have been opened
and / or committed by Lucene 8.6 or above.
