TSDB: keep duplicate series records in checkpoints while their samples may still be present (#16060) 
Renames the head's deleted map to walExpiries, and creates entries for any
duplicate series records encountered during WAL replay, with the expiry set
to the highest current WAL segment number. Any subsequent WAL
checkpoints will see the duplicate series entry in the walExpiries map, and
keep the series record until the last WAL segment that could contain its
samples is deleted.

Other considerations:

WBL: series records aren't written to the WBL, so there are no duplicates to deal with
agent mode: has its own WAL replay logic that handles duplicate series records differently, and is outside the scope of this PR
