  D3D11: Consolidate Query allocation.
  
  This compiles the resource refactor for D3D11. The only remaining
  non-smart handles are for things like SwapChains and ID3D11Blob.
  
  This might be more easily managed by using angle::ComPtr or
  similar smart pointers instead of the Resource Manager class.
