Add missing perfmon counters to SQL collector, fix TempDB Pressure pack

SQL collector was missing 14 counters that sp_PressureDetector collects
and the UI packs reference. TempDB Pressure pack only showed Forwarded
Records/sec (which isn't even a tempdb counter) because the 8 actual
tempdb counters were never collected. Also missing: Full Scans/sec,
Index Searches/sec, Page Splits/sec, Free list stalls/sec, Processes
blocked, Lock Timeouts/sec.

Remove Forwarded Records/sec from TempDB Pressure pack in both apps.
