This commit adds a new property called last_inactive_time for slots. It is set to 0 whenever a slot is made active/acquired and set to the current timestamp whenever the slot is inactive/released or restored from the disk. Note that we don't set the last_inactive_time for the slots currently being synced from the primary to the standby because such slots are typically inactive as decoding is not allowed on those. The 'last_inactive_time' will be useful on production servers to debug and analyze inactive replication slots. It will also help to know the lifetime of a replication slot - one can know how long a streaming standby, logical subscriber, or replication slot consumer is down. The 'last_inactive_time' will also be useful to implement inactive timeout-based replication slot invalidation in a future commit.
