Added additional SQL Server performance counters (#3770)
* Included system databases in server properties, added backup/restore throughput counter, error counters, and user settable counters. * Added more resource governor counters. * Added Target and Total Server Memory counters. * Removed the c_type tag from the performance counters query, added more documentation instead.

- *Wait stats*: Wait time in ms, number of waiting tasks, resource wait time, signal wait time, max wait time in ms, wait type, and wait category. The waits are categorized using the sasme categories used in Query Store.
