Added following fields to serverStatus:
metrics.query.sort.spillToDisk: The total number of spills to disk from sort stages
metrics.query.sort.totalKeysSorted: The number of keys that we've sorted.
metrics.query.sort.totalBytesSorted: The amount of data we've sorted in bytes

Description of Linked Ticket

In SERVER-60455 we expose sorter stats for index builds in server status. Query seems to already track sorter spills so it would be useful to report it for queries in server status as well.
