tsdb/main: wire "EnableOverlappingCompaction" to tsdb.Options (#13398)

Browse source 
This added the https://github.com/prometheus/prometheus/pull/13393
"EnableOverlappingCompaction" parameter to the compactor code but not to
the tsdb.Options. I forgot about that. Add it to `tsdb.Options` too and
set it to `true` in Prometheus.
