1. [dxvk] Periodically flush handles for long-running queries …

   Some apps (e.g. Halo: MCC) misuse D3D11 queries: they'll Begin(...) a
   query, and then only afterward decide that they don't actually want
   the results, returning the query object back to the engine's internal
   query pool without first calling End(...). The query thus continues
   to remain active until the engine decides to allocate the query for
   another purpose... if it ever does.
   
   While this is misuse of the D3D API and is definitely a bug in the
   app, DXVK ought to tolerate this situation at least as well as D3D
   itself apparently does. This change will try to free up Vulkan query
   handles if they're in the available state, tracking their totals on
   the DxvkGpuQuery object itself instead.
   
   As a bonus, this change should also reduce the CPU time consumed by
   repeated GetData(...) calls, since it avoids redundantly summing
   query handle results.
