tu: support exposing derived counters through VK_KHR_performance_query

Browse source 
Turnip's current VK_KHR_performance_query implementation only exposed raw
perfcounters. These aren't exactly trivial to evaluate on their own.

This mode can still be used with the new TU_DEBUG_PERFCRAW flag. Existing
TU_DEBUG_PERFC now enables performance query mode where Freedreno's derived
counters are exposed instead. These default to using the command scope,
making them usable with RenderDoc's performance counter capture.
