D3D11: Implement some PE pixel performance metrics.

Browse Source 
Super Mario Sunshine is using a cool trick: To determine how much goop has been cleaned in ep. 6 of Sirena Beach, it counts the number of pixels that are input to the blending stage. For that it's using the PE performance registers ;)

Fixes issue 1498.
