D3D11: Implement some PE pixel performance metrics.

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.
OGL: Implement pixel metrics (untested)
Video_Software: Implement PE pixel metrics
Windows build fix.
Video_Software: Fix a small issue that prevented perf queries from working at all.
Video_Software: Add some debugging logs for PE perf queries
More debugging logs for RDilux
Video_Software: Fix stuff.
Video_Software: Fix moar stuff
Video_Software: Some more debugging logs.
